This approach is the perfect "the richer get richer" inequality engine that would run things even faster than our current system (which works pretty well already). Even the most consumerist of the super-rich spend that tiniest fraction on taxable consumables compared with any given salaried employee. Which means they have more to invest to increase their wealth (and gap between them and everyone else) even faster.
Wealth could be invested (impacts those borrowing), used on consumables (impacts businesses), or hidden under the mattress or equivalent (reduces the supply of money so acts deflationary).
I would argue that those 3 are the main downstream effects of having wealth -- and they all impact people at large enough values.

That’s the idea. Lawyers accustomed to the patronage of wealthy clients need more of them to maintain their lifestyle.
