I think the "temporarily embarrassed millionaire" idea is overstated, most people I interact with have a somewhat negative outlook on the economy and their future wealth.
I think the real issue is that no viable alternative is presented to most people.
The alternatives presented are Russian-style authoritarian oligarchy, Islamofascism, or a Venezuela-style "socialism" in which the narrative only focuses on poverty.
Ah the good old "but you support Trump" debating line. Truly you are a paragon of mental acuity.
