Considering that incomes grew faster over the past decade for the top 1% than at any time in 100 years, its pretty safe to assume that the rich aren't being dragged down by taxes.
I stated the top 50% pays 97% of the taxes, well I will expound on that further, if you make $60,000 or more you will pay 85% of the taxes this is classic class warfare especially considering;
The Earned Income Tax Credit (EITC) sometimes called the Earned Income Credit (EIC), is a refundable federal income tax credit for low-income working individuals and families. Congress originally approved the tax credit legislation in 1975 in part to offset the burden of social security taxes and to provide an incentive to work. When the EITC exceeds the amount of taxes owed, it results in a tax refund to those who claim and qualify for the credit.
To qualify, taxpayers must meet certain requirements and file a tax return, even if they did not earn enough money to be obligated to file a tax return.
The EITC has no effect on certain welfare benefits. In most cases, EITC payments will not be used to determine eligibility for Medicaid, Supplemental Security Income (SSI), food stamps, low-income housing or most Temporary Assistance for Needy Families (TANF) payments.
Workers with low wages who do not have a child might be able to claim the Earned Income Tax Credit (EITC). Childress workers with low-income are believed to be the largest number of taxpayers who do not claim the credit.
If you are 25 years old but under age 65 at the end of the year and had low wages or other earned income you may be able to claim the credit. If you are married, either you or your husband or wife must be 25 but under 65 at the end of the year. Check here for the income levels for this year and prior years. Also, you may be able to claim the credit for the last few years.
You can find out if you are eligible for the EITC by answering a few questions and providing basic income information, using the IRS' online EITC Assistant web tool. It's available in English and Spanish.
In short, to qualify for EITC, you must meet the following rules:
Must have a valid Social Security Number
You must have earned income from employment or self-employment
Your filing status cannot be married, filing separately
You must be a U.S. citizen or resident alien all year, or a nonresident alien married to a U.S. citizen or resident alien filing a joint return
You cannot be the qualifying child of another person
If you do not have a qualifying child, you must:
be age 25 but under 65 at the end of the year,
live in the United States for more than half the year, and
not qualify as a dependent of another person
Cannot file Form 2555 or 2555-EZ (related to foreign earned income)
For 2007, you investment income must be $2,900 or less.

On top of this, 680 billion dollars, the highest expenditure by government, was spent on social programs. Hence contributing to the national debt which the U.S paid 480 billion dollars in interest payments....see how social programs and an unfair tax system pulls down the country??
