The wealthy can afford to pay much higher rates, and still live very comfy lives. For some reason, conservatives are very concerned about the well-being of the rich, but they don't need to worry about them. They will still have plenty of wealth under higher progressive rates that liberals would prefer. The right has convinced itself that liberals are a bunch of confiscatory marxists who won't be satisfied till the rich are shot against a basement wall, like the Romanov family. We aren't communists, we are liberals. And the Right's failure to see the difference is one of the reasons why they've been losing.
You have corrupted the definition of Liberal, in the same way the Nazi's have corrupted the definition of Holocaust. Liberal, was not supposed to mean Totalitarian. Liberty, should not be your enemy, neither should voice be, or the concept of Private Property. Rich or Poor, each is entitled to the fruits of their own invention, discovery, labor, idea, without punitive cost. How long must deny the principle of Government by the consent of the Governed?
Here is a project for you..... How about considering Health Care Legislation, a Tax Code, that's 1000 pages or less, then bring it down to 500 pages. Simplify. Remove every Impartiality. Good luck with that.
