> The majority ~70% of wealthy people in the US are self made and didn’t get an inheritance.
Not sure if where you got that number, but even if 30% got their initial wealth from inheritance, that's still a substantial fraction. I've witnessed the phenomenon in person, though unfortunately it wasn't I who was receiving the money!
Even if the majority are self made, that doesn't take away from the point that there is more than one way to wealth, and that it doesn't just boil down to compound interest.
> Also financial advisors, wealth managers, portfolio managers whatever you want to call them are a scam.
They are, and they aren't. Many people, even those "smart enough" to get rich, need someone to manage their finances, and are barely capable of doing it themselves. However, they aren't better off with a housefly as their financial professional. Many financial professionals are bozos, but some do their job well, and when you not only have the wealth to acquire a competent one, but possibly a social network that can connect you to one with a reputation among other wealthy people, then you have a good chance of being better off than a non-rich person picking an off-the-shelf financial advisor.
