It can work because it has before. Although you can debate whether it is better or worse than what we have.
The solution to Capitalism is perhaps only to keep what works and change what doesn't. I only regard Marx and an economist. He is no better or worse than Adams. Both see Capitalism from different angles and both make a strong case for what can and cannot be achieved from it. I don't think Chinas growth is coincidence. They are what all economic models should inspire to be. But perhaps they are not the political model we should follow. But thats besides the point. Enterprise should be kept to the Free market and China does that. Everything else run by the state. The Soviet Union knew how to educate, house and treat their populous far better than America do today. They just couldn't compete with the Capitalists free market and ultimately that is what broke the Union not Socialism. Gorbachev was too late with Perestroika. But that doesn't mean it was a failure. It made Russia what it is today. It no longer is just a ice wasteland. It is a superpower. And one with little debt. And should dollars become monopoly money, I believe is a state that will perhaps revert back to it origins although this time perhaps less secular.
The economy of the USSR collapsed because it couldn't adapt to changing circumstance fast enough.
You're going to need to do some fancy dancing to convince people the same wouldn't happen to us.
