I don't get why this obsession with undefined "risk" is so important. What's the absolute worst case scenario? Their business shuts down and they have to go work for a wage like everyone else?

The risk is losing their life savings or having debt the likes of which makes your student debt look like nothing. If the risk means nothing to you, you should try it, make a great business that follows your ideals, and if you fail no big deal, right?

Economically, China, Cuba, and Vietnam operate under Marxist governments using different approaches to planned economies that place a large emphasis on worker power within businesses

As I suspected, your examples are of countries that are not exactly great places to live, and where US companies go to get the cheapest labor they can. They have worse workers rights than the US

Nowhere on earth aiming for socialism isn't in a process of active struggle against the global capitalist powers-that-be, and that struggle looks very different under different circumstances

It sounds like we really shouldn't be trying for that if it only works when everyone does it. It's one thing to try and change a country, but to change the whole world? Might as well be impossible.

I don't just want the US to change to the Chinese model or something, but I do want an economic model much closer to the examples I've given here, though substantially adjusted to the conditions of the US (and the need for the US to make reparations for imperialism).

I just can't picture how that would look though, which is why I asked for the examples. It sounds like there really isn't a great example of where you think the US should go?
