But we don't have that knowledge. Economists disagree on many foundational questions. At some point, economics shades into psychology and we certainly don't have theories that predict human behavior.
I don't discount the possibility that knowledge can help economies run more smoothly but you're understating the difficulty here.

The idea that the USSR had one economic crisis is a bizarre joke. The only way you can justify this comment is to ignore all the shortages and poverty and make some tortured semantic argument about what constitutes a "crisis".
Empirically speaking, free markets trounced centrally planned economies in the 20th century. If you can't recognize that, I'm not sure why anyone would take you seriously.
I said that the USSR had one economic crisis that wasn't due to exogenous circumstances. Which is true.
I agree that free markets outperformed them. I'm saying there is clearly potential for improvement since the USSR was so dysfunctional and was planned with pen and paper.
Inequality is necessary to some level but empirically it's possible to make it much smaller.
