The Soviet rocket program failed a lot, but they covered it up at the time. It's largely come out in the time since then, and it was horrific. If NASA lost an astronaut, everything shuts down and they figure out what happens. When a test site in Russia blowed up and kills over 50 people, including the head of the development program, that's just Tuesday.
capitalism was able use space technology to improve the lives of the working class capitalist parasites better than a supposedly communist system did.
FTFY.
Nah, I like my version better. The proof is the machine you're using to type this.
Also, I'm a socialist. I just don't think the USSR was very good system. There's both positive and negative things to learn from it, but the most important is "let's not do that again".
