(You've sufficiently established your personal opinion that capitalism > communism but that's kind of irrelevant to the actual claims you were making)
What assertion are you lacking citation for? The hubble and webb telescopes vs the ??? communist space telescopes? Tony Hawk vs the ??? communist skater? John Carmack vs the ??? communist game developer? VW and Toyotas 20 million cars per year vs Trabant?
Maybe you could provide some examples of how communism has provided opportunities to all in a way that capitalism hasn't?
