An individual giving money to good causes will always be limited by the fact that it is based on the whims/biases of that individual. So, it is possible to see that some billionaires like Bill Gates and (dare I say it…) J K Rowling give substantial amounts to charities - we can also see that they are donating to personal pet causes. Society already has a way for rich people to give to a structured system that (attempts to) give(s) out the money to a wide variety of causes - its called tax and the system is government! If these people who society has allowed to become so wealthy just paid taxes and supported a proper, fair government then they wouldn’t need charities… but then they wouldn’t get to name buildings after themselves.
