I would. Why wouldn't you bet on it these days? It's also not as if any country can do better as basically every country has declining fertility rates.

And either way I was specifically responding to the point the commenter above me made, that capitalism can't help fix the issues, and my point is that China is fairly capitalist yet they've found ways to fix at least some of their issues. Not sure why you took that to mean that all of their issues will be fixed, that's a straw man.
