I used to see it all the time as an auditor in accounting. Regulations are set to stop companies from doing things. But oddly enough the more specific the regulation, the more it gets manipulated. When you compare Europe to the US, it turns out something like this:

US - You can't spend more than $X on this, unless Y applies. But if Z applies you have to take into account A, B, and C. Europe - Don't be a jerk

I agree people shouldn't be megarich. I just think we need a better way to tackle the disparity than setting a blanket limit on how much someone can own. Maybe limit income to a % of the lowest worker's salary? Idk, even that has loopholes.
