>This is also the reason why wealth dont survive over generations .
There is loads of counterexamples for this though. Especially in older countries in Europe it can become very apparent.
Also having wealth (trough inheritance) enables one both more opportunities and reduces risk.
A poor person taking a "gamble" on a business (if they can start one that doesn't require long rampup or capital) will struggle to feed themselves if it fails. A rich person (if not just focused on inherited assets) can try multiple times and is often encouraged to because of this but also trough exposure to fundamentals from family.
