OK, I guess you have not spent enough time around rich people. Rich people don't pay capital gains taxes. Rich people "in general" own assets. And in "general" those assets are in a trust. There is a trillion dollar industry in this country in the creation and management of trusts. We're talking about the top 1% here, not some doctor making 250k a year. That's one of the reasons why the top 1% laugh at the idea of paying higher income taxes. They don't have any income taxes. They don't pay capital gains taxes and their properties are in trust. Are you starting to get this now?
Now as to your left wing dribble about the poor paying all the taxes. The poor pay zero income taxes. Yes, they do pay excise taxes on goods and services but those goods and services are ironically enough being paid for them BY tax dollars in the form of gov't transfer payments. So the problem we have here is, like the OP, you are struggling with the basic concepts of money and how government works. You know enough to start shouting things into the wind, but not enough for those things to actually make enough sense.
Now let me make one thing clear. I'm NOT in disagreement with you or the OP or Martin for that matter that there is not a huge gap in equality. My argument is that your presentation of the argument is inaccurate and we both seem to have different solutions top remedy it.
