Excess capital can be invested in our future. Humans’ ability to invest in the future for our children, grandchildren, and the world is directly correlated to the amount of capital accumulation.
If everyone had just twenty dollars in their pockets, we would all be focused on finding water and food.
As we accumulate more capital, our focus stretches into the future. There are many examples of very wealthy people who invest in very long-term projects that governments just aren’t structured to tackle, because of the short-term self-interest and risk aversion of politicians and bureaucrats.
Wealth redistribution is like killing the cow for the meat and depriving the yet-to-be-born children of milk. Once the wealth is distributed, investments in new technology, infrastructure, medical advances, farming, and human well-being are reduced.
