I wasn't alive back then, so I guess you mean

in the me*

there was literal outright colonialism in the 50s, white people don't get this

Oh I know what you meant, exactly. It's grade school history. It's also the same take repeated endlessly on internet forums where pedantry and needing to spell out every single facet rule supreme. So I guess I'll spell it out. "The economy refers to the fact someone was able to pay for a home, family, and yearly vacation on an entry level, high school diploma as the only requirement job. The civil rights and liberties people are stating as the one thing they didn't want to bring to modern times."

I'm going to assume you know why someone would want that without the abuse of minorities, immigrants, or third world countries.

Or you can just pull the same thing everyone else does and state, "A society like that couldn't exist without that exploitation." like the true unique free thinker you are. To which I say prove it. We've always had a rich parasite class that needed exploitation, those who are fine without being far wealthier than others are perfectly capable of doing fine without the exploitation, its the leeches that require it.
