Some People Just Don't Get It

See this letter on the 24th in the TU? A Michael Hall writes in to say, like a good like MorOn, that the "rich should pay their fair share". Get this carp:

The issue is if you make 85 percent of the income, then shouldn't you also pay at least 85 percent of the tax?

Oh, bravo, sir. Bravo! Please, you belong in the ranks of the conservatives! We couldn't agree MORE! You see - the "rich", the top 1% in America 40% of the taxes...so by Mr. Hall's reasoning they should be making 40% of the income, right?

No.

The top 1% only make 20% of the money...but pay 40% of the tax!

That's fair, Mr. Hall? Fair is making them pay 20%...and making the bottom 50% that pay NO TAXES pay "their fair share"...how, exactly, is 0% a fair share for anyone that makes more than $0?
