Here's an excerpt:
First, the data. The top 5 percent (those making more than $153,542 — the group whose taxes Obama seeks to raise) pay 60 percent of all federal income taxes. The rich (aka the top 1 percent of income earners, those making more than $388,806 a year), according to the IRS, pay 40 percent of all federal income taxes. The top 1 percent's taxes comprise 17 percent of the federal government's revenue from all sources, including corporate taxes, excise taxes, social insurance and retirement receipts.
Barack Obama and his wife, Michelle, earned between $200,000 and $300,000 a year between 2000 and 2004, and they donated less than 1 percent to charity. When their income soared to $4.2 million in 2007, their charitable contributions went up to 5 percent.
Joe and Jill Biden, by contrast, made $319,853 and gave $995 to charity in 2007, or 0.3 percent of their income. And that was during the year Biden was running for president. Over the past 10 years, the Bidens earned $2,450,042 and gave $3,690 to charity — or 0.1 percent of their income.
