If your family sits down for dinner and one person gobbles up all the food before anyone else eats, were they within their rights? Will the rest of the family ever invite that person to dinner again?
No. We implement these controls on consumption in all areas of life. "Limit 2" when there's a coupon, for example. "All you can eat" restaurants don't allow take home and sometimes charge you for what you do not actually eat.
We must limit the wealthy's ability to consume all the goods so there are goods left over for people who need to live in them.
How does this not make sense? Why do you think it's better that someone owns 2 houses leaving 1 without a home, than two families owning 2 homes (one each).
Isn't that a better world?
