Just to highlight some things you maybe glossed over.

Your graph of share of children earning more than their parents, it shows this metric has been pretty flat for everyone born since 1960. This is not a millennial thing and starting the graph at 1940 also distorts the data. The real message is more than half of all children end up earning more than their parents.

WTF, you had your first kid at 46 years old. At 46, I had grandkids.

I think you misuse "rich" should be "wealthy."

Do you see money in there anywhere.

You are right to accumulate wealth it is necessary to earn more than you spend. More important is not having unproductive debt. It is hard to earn more than you spend if you have unproductive debt.

You do have a lot of good stuff in the story.
