But this is not because they don't get enough money and more money would fix it (well, it it could be $trillions then maybe but it is never going to be that). It's because they don't have the right tools (widely understood) to manage their money properly, and their income structure is unlike income structure of many regular people (huge sums for very short period, then nothing - as opposed to much smaller sums over much longer period) and it requires very unobvious actions to make it work. If you have literally millions of dollars in your account, it's very hard not to buy some nice expensive things - even if you know you'd need those millions for decades to come, your brain doesn't really work this way. Some people manage it properly and create brands and side businesses for themselves or just live with reasonable expenses and are ok. Some spend too much and end up broke.
