please test it properly before putting it in production, communism went poorly

note that I am not arguing that better system is impossible - that would be silly

but "destroy capitalism" attempts went remarkably badly so far

The experiment "capitalism" has already failed. You simply refuse to acknowledge that fact.

The idea, you would have to produce a turn-key solution, beta-tested on "somebody else" is obvious nonsense and pure deflection.

In the given dire situation, you have to do the best you can, not wait for some imaginary perfect escape hatch to appear.

It failed less than communism and feudalism. Which other alternatives you see?
