Claiming socialism had “barely any social climb except at the beginning” unlike capitalism is not something that you can do while maintaining any shred of honesty. The reality is objectively the complete opposite. While there are plenty of valid criticisms of the USSR, access to education was not segregated by wealth, top universities were open to all who knew their shit, and throughout its entire history party leaders tended to come from humble backgrounds.

Now, compare the above with the USA.

Hey I am all for socialism, most functioning nations have some high level of socialism in play. The issue here is a full blown case of black and white ism.

Nationalized healthcare, Nationalized oil and gas, Nationalized education, Nationalized utilities, Nationalized violence. All in place in most civilized places. Someone owning a farm is not the issue, its someone owning the place that buys the grain and controls the price.
