what is communism?

well not a noodle story!

In China, politics is communism, but economy is capitalism.
First of all, I wonder was "is it possible to be mixed"
But it's mixed...
anyway, what I want to say is they keep communism to maintain a few percent of people as previlege. I mean made them being richy richy people.
Government officer, and some worker those who connected government are really really rich.
It just crazy crazy.
But look at country side, even a little kids working for making their lives.
There's huge "GAP"
It's not fair. Communism is mean "Everybody are equal"
In China, it's definitely not.
How come?

Right now I persuade myself "that's China"
