Socialism is not really an option in the material world. There can be no collective ownership of anything materially scarce. One or another faction will assert control in the name of society. Inevitably, the faction will be the most powerful in society -- that is, the state. This is why all attempts to create socialism in scarce goods or services devolve into totalitarian systems of top-down planning.
Even the richest person, provided the riches comes from mutually beneficial exchange, does not need to give anything "back" to the community, because this person took nothing out of the community. Indeed, the reverse is true: Enterprises give to the community. Their owners take huge risks, and front the money for investment, precisely with the goal of serving others. Their riches are signs that they have achieved their aims.
There is only a certain amount of wealth in the world, this thinking goes. Economics is a matter of acquiring and allocating, not creating. This was the view of the world’s smartest people, all top philosophers and not stupid people, for many thousands of years before the age of the enlightenment. It still is.
But now I understand something more fully that I once only understood abstractly. I see how utterly ridiculous it is to think that the state can be the right means to help those who are poor or living at the margins of society. The state is their enemy, as it is for everyone else.
