The proposal is what the proposal is.  That proposal is that rich conservatives get their taxes cut.  Middle and lower class conservatives keep their taxes where they are.  Anyone who is liberal has their taxes raised.

The added feature of getting benefits or not can be added.

I'm confused though. Where are you getting these aspects from?

Liberals favor the middle class, meaning rich taxed more middle and poor taxed less.
Conservatives favor the upper class (job creators), meaning middle and poor pay the same or more, upper pays less.

Just curious.

I have even better idea

Conservatives can pay less and will not be eligible to receive social services that they feel are not governments function to provide
Liberals can pay more and be eligible to receive social services they think government should provide

Oh and let people including liberals choose whether their service provider is government or private.

Free market wins :)

Just going with the logic of what the political sides are calling for and holding them to what they want.  I am going further than the "pay it if you want to" by making it so it happens, based upon political views.  The ideas of liberals paying more taxes means that you make all them pay more, because they like tax increases.  Because conservatives don't like this, and want the rich to get the tax cuts, you end up cutting taxes on the upper end and hold it flat to everyone else.  This hold it flat to everyone else is a compromise, to reward them for wanting to slash taxes on the upper end.  Since they believe it so much, there is no reason to have middle and lower tax conservative get tax cuts, because they support them for the rich, irregardless if they get any themselves.

Who said anything about charity? Welfare is not charity. That you would refer to it as such shows me that you're rather ignorant of the purpose of welfare.

Warren Buffet is trying to make a point. Nothing wrong with that. He's actively calling for his taxes to be raised. In the meantime, when Congress start claiming all sorts of things against him, he sets them a challenge - he'll put up, if they do. It's part of a series of political movements to try to get things fixed. First he came up with the "Buffet Rule", regarding taxes for the rich. You know what the Republicans did? They made a bill, called the Buffet Rule Act, that put a checkbox on IRS forms allowing people to more easily donate money to the government. So he said "well then, I'll put up if you do", and challenged the Republicans to put up the money themselves. And when Republicans complained that Democrats weren't included, he expanded it to include Democrats.

But more than that - what point is just giving more money to the government, if the government is currently deadlocked by a party that is dead-set against any welfare spending, dead-set against any tax increases for the rich (not nearly as worried if it's for the poor, though), and dead-set against anything a liberal does? What Buffet is trying to do is to change the system. You think that a few uber-rich liberals giving a billion dollars each will make much of a dent in the debt? You think that Buffet giving a large amount of money to the government would actually inspire the Murdochs of the world to do likewise? If you honestly believe that "he should leave by example" makes sense, then you're less intelligent than I though.

Government works by everyone doing their part. That's how SOCIETY works. Conservatives seem hell-bent on destroying society by turning the system into an "every man for himself" arrangement. And demanding that liberals act independently even as conservatives do everything they can to sabotage the system is just ludicrous.

Idea is to effectively address a common problem.  Idea isn't to score some sort of "I am consistent" points on a mythical scoreboard you have in your head, that you could care less if they actually do it.  You only bring up, "well if they like it so much, they should do it!" argument, because you want to try to end an argument by showing they are inconsistent.  There are things in life where, if insufficient numbers participate, it will fail.  So, why should they contribute more, if it doesn't resolve the issue?

If you want to go with something more useful, look at my original proposal.  Have all those who want to see taxes on the rich, have their tax rates raised (aka, liberals) and have those who want to have the tax rates on rich reduced, lowered.  It is the same thing as what you want, but would actually make a difference.  Well, maybe it is a bit too "collective" to you.  Apparently, the idea of more than one individual doing the same thing at the same time is a concept you probably have a hard time grasping.  Life isn't just a bunch of autonomous individuals working in an uncoordinated manner, doing whatever their whims desire.

The FairTax^SM Plan

Your money, your decision

The current federal income tax system is clearly broken -- unfair, overly complex, and almost impossible for most Americans to understand. But there is a reasonable, bipartisan alternative that is both fair and easy to understand. A system that allows you to keep your whole paycheck and only pay taxes on what you spend.

The FairTax is a national sales tax that treats every person equally and allows American businesses to thrive, while generating the same tax revenue as the current three-million-word-plus word tax code. Under the FairTax, every person living in the United States pays a 23% national sales tax on purchases of new goods and services. This rate is equal to the lowest current income tax bracket (15%) combined with employee payroll taxes (7.65%), both of which will be eliminated.

--------------------

I realize that 23% sales tax might sound outrageous to some, but this really is a great solution. Get rid of all other taxes except for taxes on new goods and services. You keep all the money you make and don't have to pay taxes unless you spend it on something you want. The rich don't get out of this because if they buy a million dollar car or 5 million dollar house they still have to pay 23% sales tax. It is fair because the rate is the same for everyone and it rewards people for saving their money.

Uh... Europe doesn't have a flat tax system....

it has a progressive system.

Like the US.
