Two people are stranded on an island. One person has a trillion dollars in cash and the other has nothing. It doesn’t matter if the trillionaire pays the other person one dollar or a trillion, the other person will not be able to build an airplane to get either of them off the island.
The above example also applies to the entire world population. An infinite amount of money does not mean an infinite amount of output. If we want to change the world we must understand that money can’t change the world, only human allocation can. If we want to cure aging, for example, we need to have more researchers. So far money has been our best system for human allocation. There is, unfortunately, not a very strong connection between changing the world and making money. A person in Africa building wells that will save thousands of lives might make significantly less than a Starbucks franchise owner.
To fix this problem involves mixing both capitalistic and socialistic ideals. Money that is collected in the form of taxes need to be distributed based on performance of philanthropic capability. This of course is currently faux pas because anyone who is doing charity work shouldn’t be making good money and this is completely backwards thinking. If money is our best method for human allocation then people doing things to help the entire world should make the most. Philanthropy should be a competition; we should be competing over who can feed the most people.
Bother conservative and liberal ideology are incorrect in regards to economy. While private enterprise can create quality, it cannot create wide spread quality. In contrast, while governments can create universal services, it cannot create universal services at peak quality. The best political system is one that utilizes socialism for infrastructure and capitalism for quality services on top. Infrastructure includes everything that allows humans to physically survive; these include water, air, shelter, military/police, food, healthcare, roads, fire fighting, and garbage collection.
