This is why Gates, Zuckerberg, Soros, et al., are all mega-leftards. Trump is another matter. Building high-end real estate and country clubs is itself a big business. There are no mom and pop skyscrapers in Manhattan. Mara Lago is unique, and just getting together enough contiguous land for a golf course takes anyone with a shoestring budget out of the running. So the only competition is other big-time developers trying to buy the choice parcels. Regulation is a hindrance, not a help, to a large development, no matter how high your budget is. It’s a license to bureaucratic a$$holes to hint subtly that they want to be paid off.
When Buffet goes and cries about how his secretary pays more in taxes then he does and that is wrong those tear are pure crocodile. He pays the taxes he does because he lobbied and loopholed and paid people to make sure it happens that way. He can put on a show because he knows that this will not change. He won't get hit with a higher bill. The people who work for him will. That will keep them from being able to go out and start up a company that might someday topple his empire.
