What does that matter for, though? The people in that wealth bracket tend to borrow against their assets (or use more convoluted schemes) rather than use those assets directly, and someone with $300B is still bound to have a lot more borrowing power than someone with $3B. Just because they can't put these hundreds of billions in a pocket right now doesn't mean that the power those assets grant is any less significant. And if someone that rich wanted to sell those assets, it's not like it's impossible to do. Is there anything besides having to stretch out the selling over a longer period of time that would be an inconvenience?
