Firstly, and most obviously, because they introduced capitalism to China 30 years ago and thereby cut the world's poverty rate in half!!
What could be more heroic than that?
um, what the Chinese have isn't really "capitalism".
They are still run by the communist party and franchises are still handed out by the Party/State.
What China and multi-national corporations did was move manufacturing to these poor people and take away our middle class lifestyle.
But most of China's 1.3 billion people still live in grinding poverty, and the wealth disparity between the wealthy and poor is really going to come back and bite people in the ass.
We will be paying for this bit of "heroism" for a long time, I suspect.
