Thing is, those things had to be fought for and paid in blood (Literally, look at the history labor conflicts which involved plenty of massacres and assasinations).

And these struggles were only successful because 1) WW2 had militarised the working population 2) the Soviet Union was a powerful threat to the bourgeoise and 3) the profit rate was high

By the 1970s, all 3 conditions had started to disappear, and the oil shock gave the capitalist class the opportunity to pull a soft coup essentially and embark on their project of destroying the positions of the international working class movement. The crowning jewel of their achievements was the destruction of the soviet union and the opening of China, which allowed a recovering of the profit rate.

Today, we live in a world where the capitalist class won the battle of the 20th century. In these conditions, no "principled politician" or insider will be able to win you any rights. Only under changing conditions (the recent ascent of China, the fall of the empire, the profit rates falling again) will the political state of the world substantially change. And frighteningly enough, the changes in the conditions we are seeing will mostly likely lead to at worst, a new world war (the lead up conflicts are already underway) or at best, a new cold war.

The world the previous generations lived in has long vanished. 2024 America is not 1955 America. Nor is it Europe (where the bourgeoise has never had a racialised underclass to easily exploit and undermine worker bargaining power, although this is beginning to change). What might work in 1960s America or Europe won't work in America today.
