Income inequality is not the flagship issue people want it to be. It's a trend that has adversely effected people, yes, but for the most part (
read), poverty levels are down to historical lows, and trends show it stabilizing at around 15%.
Wealth distribution and concentration isn't fair, and it gives many corporations and wealthy people advantages the rest of us don't. To be sure.
But it's not
the definitive issue of our time. The country is the best it's ever been to live in. Violent crime, trending down, firearms related deaths, trending down, disease, hunger, poverty, et al, trending down.
There are obvious issues that need to be addressed, stagnant wages and cost of living are one of them (and more important than the wealth gap is the adjusting of income to livable levels from state to state, not just at a federal level). But the country isn't shitty.
The US is still a great country, it's just got issues, just like every other country on earth.
