What you don't seem to understand is that liberalism does not reject capitalism. Limiting extremes of poverty and wealth is not the same as eliminating extremes of poverty and wealth.
Where did I say that liberalism rejects capitalism?
No Government can eliminate extremes of poverty and wealth.
The more that government tries to do that, all it does in make the poor, poorer as well as the middle class. Then it becomes miserable for all.
Then when everyone is miserable, they rise up to overthrow the government and that always ends up in total tyranny.
If you know history, it happens over and over again with the same exact results.
Marxism, socialism, and communism have nothing to do with a free market system.
What part of a combo of all three are you not understanding?
That's why liberals have huge regulations that hold back the free market system.
If liberals were for the free market system, they would not keep adding tons of regulations on businesses. It keeps them from expanding their business and hiring more employees.
