I don't know enough about China to reply, only that I've heard that they are probably the most capitalist nation in the world. If I have time, I can try to substantiate some of those claims.
I don't like to drag politics into this. Republicans always talk about tax cuts. I don't know what the democratic panacea is, but I suspect it's equally based on belief and political ideology and not on fact. People in politics just stick to what their party says and worry about being popular, not about doing what's right.
[quote:nz74erdl]To me, it seemed the neoconservatives (Republicans) were pushing classical economic theory, the idea that markets regulate themselves. I think this was/is an outdated notion and we're seeing a return to Keynesian economics which operates from the premise that hat private sector decisions sometimes lead to inefficient macroeconomic outcomes.

Now this is a very interesting point. The trigger of the whole crisis was mortgages and their securitization. Government actually had a huge part in this, in promoting home ownership (subprime and alt-A) and lowering interest rates. In a healthy, non government interfered mortgage market, subprime and alt-A should never have left the ground. This topic is huge and should probably be dedicated in another post.
About the Keynesian part, you still have to answer those questions I posed.

[quote:nz74erdl]This is why we're seeing such an emphasis on stimulating demand. The Republicans are holding their ground and saying that we should just continue cutting taxes because taxes are holding back the potential of the free market. Personally I think they're doing it for political reasons, not because they still believe in outdated economic models.[/quote:nz74erdl]
I agree.
