Work Reform

In my experience in my own country as well as living in other countries (none of which the US, but I believe it equally applies), leftwing policies (such as universal schooling and worker rights) built the middle class and the Neoliberals (which are generally the two major parties in a country) have been destroying it since Reagan's days.

For me this was especially obvious in the UK were almost every single pro-people thing (National Health Service, Social Security, Public Housing) dated back to the years of Labour Party government immediatelly after WWII and every single one of then had been under attack in some way since Thatcher's day, including during governments of New Labour (the Labour party after the Neoliberal faction took it over, most obviously with Tony Blair whom Thatcher called "my greatest achievement").

I think the UK is especially applicable here because it's the country in Europe that, at least for the last 2 or 3 decades most apes the US (in the bad things, rather than good things).

All this to say that I don't expect ANY American politician who has managed to hold to power for so long as Mitch Mcconnell to be anything else than a middle class destroying Neoliberal, no matter what political party they come from.
