That's not what anyone is trying to convince anyone of. The argument is that many of the rich pay a lower rate of taxation than you or I do.
That's not true.
You're not repeating Buffet's lie about his $60,000/yr secretary paying 30%, are you?
It doesn't matter what his secretary pays. You teabaggers are so easily distracted by irrelevant details, you're like 5 year old children.
Its a FACT that the long term capital gains tax rate - 15% - is LESS than the average tax rate paid by MILLIONS of middle class taxpayers.
Warren Buffet doesn't have to pay FICA taxes on his capital gains - not a dime. Us middle class have to pay FICA taxes on every cent we earn up to around 106000. In ordinary years, FICA is 7.65% - that's already more than half of the 15% that Buffet pays.
A take a nuclear family of 4 that files jointly. The combined income of mom and pop is $90,000. This is above average household income - but hardly living large.
Their standard deduction is $11,400
Their exemptions are 4 X $3650 = $14,600
So their AGI is $90,000 - $11,400 - $14,600 = $64,000
They pay 10% on the first $16,750 of that income, for $1,675
They pay 15% on the remaining $47250 of that income, for $7087.50
They get $2000 in child tax care credits.
Their total ordinary income tax is therefore $6762.50, which is about 7.51% of their income. Add that to their FICA taxes - and they pay 15.16% of their income to the federal government.
What's more - if mom and pop above earn $1 more than $90,000 its taxed at 15% + 7.65% = 22.65%. If Buffet earns $1 more in capital gains - its taxed at only 15%.
