But in the 60’s it was on its way to eradicate the bourgeoisie and lift the under class in its entirety?

No, it was just a welfare state back then too, they just had more concessions at the time because there was the Soviet Unions just next door with guarantied employment, free healthcare and housing, etc, and were getting so riled up over it that the bourgeoisie was getting really scared of potentially having a revolution and decided that temporarily giving these concessions was better than loosing everything.
