I don't think that's entirely fair - let's say your parents made $500,000 a year; if you made 90 billion, wouldn't that still be self-made? Sure, it's not as self-made as Carnegie or Rockefeller who would have been 10/10 as child-laborers turned wealthiest men in the world, but it's not exactly Trump or JP Morgan Jr., either.
When your parents are among the top 1% in the country (and, presumably, act as a risk-cushion in case you were to fail), it is difficult for me to buy that you are self-made.
