Lower income taxes sounds great today, but greater wealth inequality and no social safety net making wealth meaningless (population level poverty and poor social mobility make life for even the wealthy worse)
The working class doesn't think that way, on the contrary! They have to live careful as small missteps have long term consequences. There are plenty of cases where people will happily vote for austere measures, and they rather think the government should spend less.
For the ultra wealthy, everything is free lunch for them, even if that would mean you will be 10% poorer.
If the 0.01% get 10% richer, and the rest 10% poorer, than that is still a win for them. Hence why right wing populists are a great business case to invest in.
Maybe you're saying it means democracy-when-it-doesnt-select-"elites"?
- people made bad choices through deception or carelessness - populism.
