It can all be reduced to the problem of man-made law. It is wide open to abuse. So, yes, the ultra-rich abuse man-made law to make more money. But then again, machine guns easily overrule money. That is why there are now islamic insurgencies, in 30+ countries, of which the primary purpose is to get rid of man-made law (and to establish their favoured alternative). The problem goes way beyond the distribution of income. At some point, everybody who believes in the legitimacy of man-made law will have to prove that he is willing to risk his life and die for what he believes in.
Scriptural law, for example. Each religion enforces its own law. This solution may not be ideal in every possible respect, but to the extent that it puts a halt to the invention of new man-made laws, it will certainly mitigate the problem. Every man-made law represents a reduction in your freedom with the purpose of serving the interests of someone else. Therefore, I am in favour of any alternative solution that will put a halt to people inventing new laws.
A consistent set of traffic rules is a mathematical problem. Mathematics emerges from the laws of nature. Traffic rules are a prime example of what would go totally wrong if you tried to solve it with typical man-made laws. Instead of giving priority to traffic coming from the right, we would end up giving priority to traffic of the members of the elite instead. In fact, that is what happens in many countries. Furthermore, in case of a traffic accident they always find man-made "legal" reasons why the elite is right and everybody else is wrong.
