It's sort of weird that you criticize igravarious for saying "just solution" because it's an opinion (and so what? We can express opinions here, right?), but then you say that in such a system the rich would be "unfairly taxed", which is also an opinion. And yes, some rich people will probably leave the country if you raise taxes on them. But that's no more an argument against raising taxes on the rich than "if you increase the price of bananas, people will stop buying bananas!" is an argument against raising the prices on bananas. If we want to stop talking about opinions and subjective ideas, then what you're left with on that specific point is simply an optimization problem. The government is essentially selling a product, which is a big old package of laws, regulations, court systems, public programs, etc. which make the country a nice place to live and do business in. Taxes are the price that the government charges for that product, and compared to much of the world, that price is very low. So to say that all (or most) of the rich people would leave the country if their taxes increased is roughly equivalent to saying that the US is an inferior good, competing on price alone. And I don't think that many people, including most who make such claims, believe that for a second. At least, not as far as the wealthy are concerned.
