It is a very interesting notion to "earn" what they have. Fortunes are built by being in the right place at the right time with the right idea. Gates just happened to build DOS with a little help in a few months and things snowballed from there. Zuckerberg built the basics of Facebook in a couple of weeks and it took off.

The business practices of large corporations that create these massive fortunes for people like them are questionable because the very nature of their charter is to maximize the return for investors without regard for external costs.

Gates, with a little wise investment can walk to his mailbox each week and pick up dividend checks worth more that many of us can hope to earn in lifetime.

They did not fund the basic research and development creating the network of things that make computing possible. The endless assembly language stuff that goes into the computer processing and hardware that nobody thinks about. The entire sphere of support that makes this a civilized place to live. None of this stuff would be possible without the taxation that is paid for disproportionately by the poor.

If we can find a way to distribute things a bit more fairly in the first place we wouldn't need to place so much effort into trying to redistribute it later imho. There's nothing wrong with being rich or earning some big reward for your effort but at this level of compensation???
