I agree, but very large corporations (like WalMart and Amazon with high levels of vertical integration and revenue greater than the GDP of many countries) are kind of like a command-economies and "work" (for the shareholders). So, I think command-economies can work, but the question is for whom.

It really depends. China is winning the race on sustainable energy because it's treating it the way the US treated the Space Race after Sputnik.

And we are seeing how market economies go, the the outcome is dire.

I don't know what works, but obviously neither do you. Neither do our elected representatives who are captured by interests to return to monarchy (which can command the economy).

So that's, just, like, your opinion, man.
