This but replace “Marxism” with “neoliberals trying to repeat the free market economic model without eventually being rendered unsustainable due to the falling rate of profit, boom and bust cycles, and the concentration of capital into fewer and fewer hands” and it’ll be more accurate.
And saying the USSR and other socialists nations didn’t work is missing like 3 tons of nuance. For example, the illegal dissolution of the USSR by the U.S.
Please actually read some Marx before making up bullshit about his followers, this is clearly a strawman.
