Depends on your lifestyle inflation. Even for the high earners in the US, 49 million per year is FIRE money, but if you're used to the life of an oil sheikh with luxury clothing, jewelry, art, exotic private parties, dozens of rare supercars, private jets and yachts, McMansions/penthouses in London, Paris, Geneva, NY, Tokyo, etc., some private island where it's nice and warm, and also want to leave a similar lifestyle for your kids and their kids and their kids' kids, then 49 million per year is basically poverty money.
