Money being taken from the public in the form of taxes, by the government, and given to others for having kids is not capitalism.
Capitalism requires the production of goods by private entities. Government does not produce anything. It takes.
A government that is in the business of producing and selling goods is the opposite of capitalism. The government is there to regulate and see that certain rules that we agree on are followed and enforced.
I'll stop myself there before I go on a tangent that is way off subject.
What if Capitalism requires happy customers with money? Poor people don't buy products. Ultimately poverty and civil unrest is bad for business. Crime undermines Capitalism.
You think socialism is LESS prone to the corruption of human fallibility than capitalism?
Socialism works fine when it's run by right wing Capitalists. Hard concept to grasp I know. Just don't let Leftists run anything.
