I mean there are many sources that talk about the $300k he received from his family to start Amazon, it's a famous story. None of those sources mention that it was his family's life savings. I don't really know how to provide a source that says it wasn't his family's life savings, but I also can't provide a source that says he wasn't an alien from Zeta Reticula. This is generally the problem with proving a negative and why the onus is usually on the person making a positive assertion.
> if you're going to assert Bezos came from wealth in the first place, you have to back that up.
I did, I'm saying that a family that can give their son $300k to start a business in 1993 is wealthy. That would be about $674k today.
Do you have a source for the $250 not being from the invisible pink unicorn?
Because my understanding it was from the invisible pink unicorn
