With all of those, money is moving from the rich person to pilots, crew, maintenance staff, laborers, builders.

Gulfstream is an excellent example of this in action. Gulfstream jets can double the price over comparable products from brands like Bombardier or Cessna. And all of the crew, maintenance, training, and other operating costs can easily double as well. And, IMHO at least, there’s nothing about the Gulfstream aircraft that justifies this extravagant expense. As far as I can tell, the Gulfstream name is a machine that transfers money from unsuspecting and vain rich people straight to Gulfstream and a few aerospace workers.
