I think a better explanation is small inheritances. I think there are a number of people that have come into small inheritances. Enough to change their situation but not enough to move out of their social circles and because of that they’re very unlikely to let you know.
Say someone gets $500k from their uncle. Not a small sum of money but not a gigantic inheritance. You’re not going to immediately retire if you get that but you might pay off your mortgage. Now ask yourself what your lifestyle might be if someone came along and wiped out your mortgage. Now that Jeep or Audi might not be such a big deal and your looking at them thinking, “how on earth can they be doing that? They’re working the same job I am and I can’t do that”.
