Democracy is shit at making people happy, but a nationalistic, populist state would be pretty good at it. The problem is when the government focuses too much on itself and not enough on the people.
The Shortcomings of National Socialism

The purpose of the state is to secure the prosperity and future of the volk.
All of that is bunk if the people themselves are unfulfilled. What good is material wealth or a future if it is not enjoyed. The state should, at the very least, keep the population's happiness as a central priority - countries that don't look like Weimerica, rich but miserable
The word covers happiness.
More implies material wealth, but I get your point
Hitler stated that a legitimate state grows out of the people (or something to that effect), as National Socialism did. Consider Germany a trial run. While I don't agree with your points entirely, even prominent members of the party like Goebells admitted there were mistakes in its beginning. A party for the people, by the people, will adjust itself accordingly, and 2.0 will be even better.
North America was settled by pioneers given to immense self sufficiency and individualism. It's in our genes. Europe is based on over a millenia of highly organized and socially stratified subjugation to aristocrats. National Socialism, Napoleonism, the divine right of kings comes naturally to them. Not so with North Americans.
Also as called for in Marx's writings the national socialists used conscripted battalions of unpaid workers, essentially slave labor to get things accomplished. This is theft, albeit by the state of the labor of young men in the prime of their earning years. From my point of view replacing unemployment with slave labor is not an acceptable solution. There were over 800,000 young men incarcerated into doing hard physical labor without pay under National Socialism.

Essentially this is telling the lower classes that their labor is worthless, that they are worthless and that they have no free agency to negotiate the value of their work. They are conscripted under law to labor without remuneration. Thus you are descended to the level of a helot.
