>study the US in the 1960s.

The US was a vastly different country in the 1960's than today from all points of view. Plebs had way more social cohesions and unity, and lot more bargaining power over the wealthy and politicians, when communism was the main enemy and all working class jobs hadn't been yet shipped abroad and PE hadn't yet monopolized ownership of housing and everything else and the US industrial elites didn't have doomsday bunkers in Hawaii and New Zealand.

What I'm saying is what worked then won't work now because the context is completely different.
