Consider it a ladder with 5 steps representing dirt poor to super rich and you can at most go up or down 2 steps in 1 generation.
If you grew up poor, chances to get rich and stay there is almost non existent.
It's not related to hierarchy like in the middle ages, although I'm presenting it like that.
It's about multiple factors at once.
The hierarchy of the middle ages may be gone, but personal interpretations of life are still influenced by how you grew up. That still matters a lot.
