Actually, the socialistic intervention regarding health insurabce is overwhelmingly denounced even by the people in the insurance industry. But society is unequivocally, absolutely NOT like a pyramid. There is NO limit to how many can be at the top and the wealthy get that way by CREATING WEALTH which increases the overall size of the pie for EVERYONE. It is the free market that has been directly and SOLELY responsible fior the vast improvement in living standards, particularly for the poor and working people over the last 300 years.
The notion that a wealthy society cannot produce workers to collect garbage, etc. is based on the (ludicrous) fallacy that there is no constant incentive to make oneself even more well off.
