China has lowered the air polution in their cities by a lot. They are investing heavily in renewables and fixing desertification.

I don't mean by that that China is a communist country, because it isn't. It is a dictatorship with a capitalist vision. But they are more socialist and people based than others.

Why can I say that? Because they are effectively trying to fix the problems that their capitalist vision has brought, like environment contamination, pollution and desertification.

You've given the wrong example and proven right the other comment: A strong government can fix the problems a liberalized economy can bring.
