I grew up without any family money and found the US economy ( with some advice from the Bogleheads community ) conducive to building a good life.

I now have 3 adult children, all seem to be likewise on good paths.

I truly believe the US economy offers an excellent chance to grow wealth, if patience and discipline are used. Even for salaries that are only decent. Plenty of teachers, plumbers, etc. become millionaires by retirement age. You just have to have a little luck ( avoid the rare financial catastrophe) and follow the Bogleheads trail.

About ‘the wealthy’, don’t worry about them. Just manage your own affairs, you’ll be fine.
