Let me strengthen my position by adding that it is also moral and ethical to seek a return by investing, providing you make reasonably ethical investments. Maybe not in the coal industry or whale meat industry - but any number of things can be perfectly ethical and even beneficial to society at large.

Does reasonably ethical investments include using insider knowledge?

Which is what these politicians seem to be doing. Sure it is not illegal, but is it ethical?

This took a left turn when someone started just complaining that people have a lot of money.

I'm not advocating for insider investing - which may well be going on here. That's obviously not ethical.

I made a much more general statement in my comment, which you seemingly objected to.

It is not immoral or unethical for somebody to have or earn more money than another. All people try to increase their wealth however they can. At lower income levels that is very difficult but the behavior is the same.

It fails to comply in either case.
