Readit NewsMaybe in aggregate flights have fewer delays but every single flight I’ve taken this year has been delayed (on top of the padded flight times the article mentions). I’ve flown about half a dozen trips.
I also hate the argument that the free market should solve the pricing problem. Airlines have exclusivity on airport gates. Any frequent flier on the SFO -> EWR route knows that if you want to save money you can book an Alaska flight instead of United but Alaska has significantly fewer gates and usually gets delayed when arriving waiting for one. Flights aren’t exactly equal commodities and even if the airlines were well-run, contracts for these gates are locked in.
Pricing stats here also fail to account for business class vs economy pricing. Business class prices on tickets have skyrocketed, way outstripping purported CPI. In some cases prices have doubled or more since COVID.
This has been repeated so many times that I think people don’t understand just how small the profit margins are for health insurers. Low to middle single digit percentages. As low as 2-3% in recent years, and much lower than the average S&P 500 corporation.
There are also non-profit insurance companies out there. Their rates are not appreciably different, as you’d expect after seeing how low the profit margins are in for-profit insurers.
I also think people don’t realize that countries with nationalized health care also deny procedures, have pre-approval processes, require step therapy, and will not authorize procedures they don’t believe to be medically necessary or to have enough evidence. There is no health care system in the world which will simply approve and pay for every request.
So while health insurer profit margins are convenient bogeyman, if you deleted their profits entirely from the system it wouldn’t move the needle on costs. It also wouldn’t open the floodgates for approving everything, because no health care system will allow unlimited services. The amount of excess and unnecessary care would be astronomically expensive. I do agree that we need a more robust system in place for ensuring that incorrect denials don’t happen, but health insurance profit margins are barely a blip on the overall cost of health care in the United States.
It’s a combination of high prices for services, American’s unusually high utilization of health care services, and very high rates of drug prescribing that mostly contribute to the cost. I think most Americans would be surprised to discover that a lot of nations with nationalized health care would also be restrictive in their access to many services and prescription drugs. For as much as we talk about insurance companies denying claims, Americans still get far more services and prescriptions than most of their counterparts in other countries.
1) united healthcare made 90 billion dollars gross profit in the last 12mo, and that's only one health insurance company. claiming that it's not a great business at a 2-3% profit margin ignores the scale of money involved, and ignores that the customer for health insurance is truly captive.
2) you're right that america has very high prices in healthcare. doesn't it seem bad that private insurance companies are incentivized to make things cost as much as possible so they can skim that 2-3% off the top? insurance companies negotiate and set prices for services and pharmaceuticals. they now own the pharmacy benefit management companies that would normally be incentivized to negotiate for lower prices.
i would expect in a public health care system that rejects procedures, they would follow consistent guidelines and rules. american health insurance companies will arbitrarily reject a percentage of procedures that they know they should be accepting in order to keep their profit margin in the right range.
i think it's hard for me to see the argument that health insurance companies are a net-positive or even net-neutral party in the united states. i don't think it's a coincidence that we have some of the highest prices and some of the worst outcomes.
But there is a customer experience reason. As an iOS user, I very much appreciate that I can ask Apple to cancel some bullshit subscription that used to otherwise try to lock me in behind a labyrinth of added friction and timewasting.
Not every problem is technological.
if apple was saying you had to support their payment processor alongside others (so you could opt into paying +27% and getting easy cancellations), that would be one thing, but they don't allow you to have any other options available in the app, which i think is where the anticompetitive complaints start to feel more valid.
It has insane peak power draw from its radios, much more so than any other wifi uC, and it's horribly energy-inefficient when not sleeping.
The money making part of vmware licensing is the baremetal hypervisor ESXi, the competitors are xen or hyperv and the likes.
The lock-in part of vmware is the vsphere management software, that allows you to move VM's en mass from one baremetal machine to another baremetal machine, or allows you to nest vm's, etc. manage your entire fleet of vm's which could be thousands or hundreds of thousands of virtual machines, from one management interface.
it's basically docker except it's actual entire vm's being moved around. VMWare ESXi being a baremetal hypervisor means you can run different OS's on top of these vm's and imagine being able to move these VM's all running different OS's around in your ecosystem.
That's what people pay the big bucks to vmware for.
It would be very difficult to build the vsphere/esxi ecosystem with pure opensource tools (it's possible with Xen, etc) but you'd be right back at paying some vendor a massive amount of money for building, integrating, and supporting this kind of system. (Redhat will happily sell you something that approximates vmware's tools, for megabucks).
As an aside, the consumer "vmware" software that you install on your workstation is such a small portion of their business, they basically spend no money on fixing/upkeeping. Apple silicon support was in beta for a loooong time, and they don't actually care about their workstation product. ESXi makes the money.
1. vmotion + storage vmotion - you can live migrate a vm from one hypervisor host machine to another. you can also live migrate the underlying storage (good if you want to consolidate storage servers, rebalance disk load, etc). with some caveats, you can do all of this without any downtime in the vm. it's not just a simple suspend on one host, resume on another host. a memory snapshot is migrated while the vm is still running on the first host, and when the amount of dirty pages starts to converge, they flip the vm over to the new host. similar idea for storage vmotion.
2. fault tolerance - for single cpu vms, you can use vmware's record-replay technology to execute a secondary vm in a "shadow" mode which replicates all of the nondeterministic events across the network. if one hypervisor host dies, the other can take over with no downtime. this is great when you need to add HA for a legacy application.
3. vsan - generally you run these systems with some sort of shared storage (nfs or iscsi attached SAN, or something like that). a SAN can be really expensive and a single point of failure. vmware can create a "virtual san" from a cluster of your esxi hypervisor hosts. as you can imagine, it has all sorts of HA features and can rebalance workloads to improve performance.
there are more, but that's just a few interesting features.
I swear that SF water started tasting worse after they started adding groundwater a few years ago:

personally, i was on a flight in May from SFO to EWR and my flight flew 2h30m towards Newark, then back to SFO when EWR stopped accepting landings: https://www.msn.com/en-us/travel/news/united-flight-that-was...
granted this was an especially egregious situation and not the norm, but it feels like these types of issues are on the rise based on my anecdotal experience. there were a number of full ground stops at newark due to ATC in the weeks after this. it was national news.
