When you have a hundred extended relatives reaching out for help, combined with scam artists trying to talk you into "investments", it's easy to go broke.
It's also damn easy to waste money at any scale simply due to your own financial demeanor. I waste a lot of money on $50-$500 gadgets because that amount of money doesn't mean much to me. I'm not very financially responsible, though I'm not irresponsible either.
If I made ten times what I do, I'd probably be buying $500-$5000 gadgets just as frequently. If $100k didn't mean much to me then I'd probably buy a Tesla. If $20M didn't mean much to me then I might become a space tourist.
A more financially responsible person than myself would be likely to remain more responsible as they scale up, and a less responsible person would likely remain less responsible.
