They're not poorer. They're exactly one used Xbox richer.
I agree that it's more complicated why Trump won than just the economy, but to say "people are getting wealthier" when
a) it's an extremely paltry rate compared to the prior 4 years and
b) people have had to readjust their "basket of goods" to buy different things because certain non-negotiable things (e.g. cars, car insurance, other insurance, utilities in a lot of unregulated states, property taxes outside of places with Prop 13 / homestead exemption, etc) have gone up significantly, putting a squeeze on disposable income.
I guess we're arguing semantics here, but I agree that a lot of voter decision on this is more complicated than real income. I just disagree that $50 / year increase is meaningful enough to have people not feel left behind. That is about 12 bps a year, and I know that if my raise were 12 bps, I'd feel like why bother at all / insulted. If I were a moron, I would blame the current president, but I'm not naive enough to think that it's Biden's fault.
