Two keys are missing from your analysis, Mr. Eskow.
First, the Conservative policies of people like Reagan and Thatcher didn't just emerge from a vacuum. They are the fruit of two things:
A. Funding from lobbyists who prop up those politicians who will do the bidding of the rich/corporations
B. Funding to think tanks that gave Conservative Ideology the imprimatur of being wise, sound, and good for the nation.
How then, can the monetary influence (much of it achieved through stealth) that's worked to put unfair policies into place be countered? It's not like "we" can just "do this."
WE can't get our preferred candidate elected.
We can't determine what's in our foods.
WE can't get assault weapons off the streets.
WE can't read the TPP and TIPP or vote--via referendum--on either.
So it's very romantic to talk about all the groovy things that "we" can do... however, the System has been Captured and until that capture is somehow reversed, none of this is going to be possible:
"What can we do to reduce inequality and heal some of its deep, long-lasting wounds? Here’s a partial list: We can increase funds for antipoverty programs that provide food, shelter, and other services directly to the poor. We can improve our educational system and provide tuition-free public college to all qualified students. We can address the systemic racial injustice that deprives communities of color of economic resources. We can raise the minimum wage, which has fallen far behind inflation (and even farther behind productivity) since 1968. ($15 an hour is a good number.)"
P.S.... There has been some progress made through organized efforts on the minimum wage item.
