I think the administration's energy density should be extended for all things. Lets take transportation: Can't use federal lands, waterways, airspace or highways unless the airplanes, trains, ships, trucks and cars are powered by the highest energy density (nuclear).
Also, anything that uses airwaves: So, nuclear powered phones, watches, airtags.
This would be the biggest breakthrough for humanity. We have nuclear powered submarines but miniaturization of nuclear stalled since then.
We control nuclear proliferation by making enriched uranium (U235) very, very hard to acquire.
While I'd love to see more nuclear reactors in our society. The "nuclear everything" argument breaks a core tenant of US national security policy, making U235 very hard to get.
Mass movements arise when populations, that had had large increases in living standards, find their living standards are no longer rising. Hoffer cites something like 30% of the country is now 'middle class' and then depressions etc. set in.
Take the quote, "A society so thoroughly steeped in the work ethic and committed to the pursuit of individual achievement cannot but fail to prepare its members for any other kinds of lives."
The reality is the opposite. When work doesn't pay (i.e. when hard work can't lead to buying a condo/house and starting a family) the original premise of "work hard to get ahead" breaks. And here we are.
Any civilization where two 30 year old elementry school teachers can't buy a 1,200 sq-ft 3bdr/2bath condo for less than 30% of their income - is morally bankrupt. Aka 99% of the bay area, or DC, NYC. So people tern to idleness without the ability for work to result in personal progress.
The solutions are simple: make it easy to build housing. If you're bored, deadlift. Spend time outside. And, most of all, change our national household economics to allow ownership and family formation.
