The fact is that we just do not know. But what we can actually observe is... Quite grim. And we are not even taking the smallest, tiniest steps we can possibly take to fixing it.

We are basically doing only what is STRICTLY dictated by economy. And we know that it is simply not enough. Whether in 2 decades or 10, billions of human beings are going to die from the direct or indirect effects of climate change. And that is... Incomprehensible.

Billions of people will not die from climate change, if anything they would simply not be born.

That is already happening in almost every western democracy as fertility rates have dropped precipitously. That is not because we have any food shortages: it’s because people are choosing not to have kids because life is so expensive.

Please note ICE is doing operations in blue cities against law abiding immigrants at hearings because to go after either actual criminals or the gun infested red areas would be a danger to life and limb.

Turns out, making yourself a more dangerous target works to an extent.

ICE must cast a wide net in blue cities because they are not sharing data on the criminal undocumented residents. They are shielding the illegal migrants who are already in jail or released on bond. Red areas are not shielding their criminal element and there is less need for such a wide net. Sanctuary cities ignoring the constitution and delegation of powers to do whatever they want is causing much of the escalation.

I have no idea what ads they serve me because I have ad blindness. My brain just refuses to perceive them.

Even when they float over the text I am trying to read, I do not see them.

This is a top tier super power. Ublock on Firefox and AdGuard on iPhone are pretty effective. When I actually see an ad it physically hurts.
erkt commented on Can I stop drone delivery companies flying over my property?   rte.ie/brainstorm/2025/06... · Posted by u/austinallegro

In my neighborhood (rural) a drone hovering over someone's property would be likely used as target practice.

If delivery drones become commonplace, there are going to have to be regulations about which air corridors they can use (altitude and routes) or it will be chaos.

I would hope so. The temptation to strap unknown sensors to map and analyze the customers they fly over will be impossible for them to ignore. Let the drone hunting season commence.

I thought the purpose of that was to let them avoid price matching on certain items despite having price matching policies. I have never heard of one budging on this. Have any?

It is so the manager has a policy to fall back on to say no. It is just the second round of negotiation.

I am not saying everyone will play ball, but managers whose pay is a function of sales likely will. Have you ever negotiated buying a car before? Indicating you will let corporate know they lost a sale by not budging on price will almost always win the negotiation with managers who think they can just be lazy without consequence.

In the standard retail environment, I have definitely had businesses price match products with the same specs but very slight SKU differences, you just have to be open about a willingness to forego the instant gratification because that is the only service in person retail provides today. That might mean actually completing the sale online and then asking again. They know when there is actually a material difference to the products.

Businesses that are legit monopolies will not budge.

>Retail/amazon operate at a much higher margin than most people realize.

This statement encompasses the whole business, for which the profit margin is the relevant metric, not gross margin. And it is clear that the standard retail business is not one in which you can earn a lot of money. Just because a specific item sells to a customer for more than what it costs to buy just that specific item from the supplier, does not mean the business's margins are high. There are myriad costs that have to be accounted for, such as spoilage, theft, inventory, transportation, labor, returns, etc.

Some things sell for higher margin, some things sell for lower margins, but at the end of the day, the stores clearly operate at very low margins. Hence why so many go out of business all the time, and all the brick and mortar we have left are the biggest ones with the largest volumes.

That is not what we were talking about though. We were talking about how much discount you can force out of a retailer via price matching which is a function of its Gross Margin. a 25% discount at the register doesn't mean a bottom line 25% subtraction from Net Margin. Those numbers are distantly connected and most operating costs (minus COGS) are fixed.

The 100K is a big problem.

The library doesn't even approximate a substitute. Maybe you are a genius, but almost everyone needs teachers. Even experts need people to teach them new things, to mentor them, etc. They also need labs and equipment.

Also, the library you need for real reasearch is not free. It only exists in academia. Your local public library doesn't give you access to nearly the same resources, nor the essential reference librarians. (Maybe the NY Public Library? Does that have JSTOR, for example?)

erkt · 3 months ago
You are 100% correct about the quality of the resources in a local library. That’s an artificial barrier to learning though. Aaron Swartz died because of this. JSTOR is a crime against humanity.

Libgen is a solution to that.

I agree there is value to learning with experts but not at the cost we are expected to pay these days. The labs and equipment are a tiny fraction of the tuition a student pays and many disciplines do not require anymore more than pen and paper and the aforementioned resources. Why should a math and economics major pay the same as a biochem student? Because the majority of the cost is the bureaucracy and the fancy real estate investments.

Because net profit margin is different from gross margin. The products are still marked up way higher than that bottom line number. PMn is the margin after you add in all the over head costs and those really have little to do with whether they are loosing money by selling a product under their target mark up.

Best Buy making a gross $250 on a $1000 priced TV or $50 when discounted to $800 still isn’t loosing any money unless they are at their credit ceiling and cannot replace the good sold. They make zero if A customer standing in their store deciding not to even give them $50 and giving it a to a competitor on their cellphone. Tho is absolutely profit opportunity lost, even if it is small.

Consider the case of a business operating at excessive margins with huge room to discount but doesn’t. Their fixed costs must then be spread over few transactions and lower their net margins to almost nothing. Instead a business operating at a much more socially optimum price point sells a huge amount of goods at a lower mark up and gets to spread those fixed costs over a lot more transactions. Their Gross markup may be less than the high priced store but their net margin can be higher.

I set a lot of prices during the pandemic. Any average business found that they were granted some degree of monopoly power and could generate higher net margins with less competitive prices. Many of us found the simplest solution was to just pass on all costs to the consumer because they had no choice but to take our price or not get their good.

Times are different and there is competition but many businesses have still forgotten how to increase gross margin by having a sale.

Not to get into politics but tariffs are the same way. The elasticity of demand for a good determines the monopoly power of the supplier/retailer and how much of the tariff gets passed on to the consumer. Highly interchangeable products will not see the full tariff passed on to the consumer because that would mean forgoing all sales. The importer will determine how much gross margin they can give up without loosing money…but the producer in the foreign country also does the same math. Do they completely give up the American market to save inventory for other markets or do they eat some top line profit and still make some sales.

Many goods will indeed be pulled from the market, but if the producer fails to find replacement customers in other markets they will look back at 300M Americans and reconsider whether they can give their importer a better price while still making something. If the good expires, like say a case of white wine, or becomes obsolete in the case of say a lightning charging cable there is additional pressure to make the decision before the surplus simply becomes unseeable.

If a good has no viable alternatives and is relatively shelf stable expect all tariffs to be passed along because the products price is already disconnected from its cost and the business producing it is closer to a monopoly than not.

Oh God. I wish the sales clerks would leave me alone. They’re always trying to put their sticker on purchases and proffer useless advice. Still, it’s the best in the area, and the Trader Joe’s is a draw. I bought my first computer, an Apple //gs at Micro Center at their original, single location.

Just ask for their sticker and promise you will put it on your purchase. If another approaches just show them the sticker, they get it.
