I live in California and very much disagree with the Fed as a big part of the issue (and CA only has the highest poverty rate when you adjust for cost of living - for example we have very generous healthcare for the poor with ~30% on free healthcare. Compare that to the rest states. It's a hell of a lot better. And we have something like 25% of all undocumented people in the US, as the country's leader in agriculture. So... ya, about the poverty, it's not as bad as it sounds. Our state works well overall.)
I think the country has far bigger problems now that Republicans have gotten their people on the court to allow unlimited money in the elections, now that they have a media system with control of 90% right-wing control of talk radio nationally and many other outlets, reflected in their winning a thousand more seats nationally at the same time they have driven inequality to record levels through policies.
It's the structure of the economy that's reinforcing the inequality; for example, it's not Fed that's the dominant factor in top companies' CEO pay increasing from about 25 times workers to over 300 times. Or Wall Street going from taking 10% of the country's profits to 40% - the distribution of the trillions after 2008 was a government policy choice, not the fed.
