Change You Can Believe In, As Long As You're Using Someone Else's Money, And Not Your Own
Joe Biden's income and taxes 1999-2008, via TaxProf:
IRS statistics reveal that the average taxpayer with AGI over $200,000 makes over $20,000 of charitable contributions:
$30,000-$50,000 AGI: $2,158 average charitable deduction
$50,000-$100,000 AGI: $2,703 average charitable deduction
$100,000-200,000 AGI: $4,057 average charitable deduction
$200,000+ AGI: $20,434 average charitable deduction
Update: A comment by David Rotor criticized the chart above for including Biden in an "unbanded range" of $200,000 in AGI and above, which includes Bill Gates, Tiger Woods, Oprah, etc. But the analysis above also compared Biden to the lowest income group, showing that he was even less charitable than the lowest income group ($15,000 to $30,000). The graph below includes the charitable contributions for the income group below Joe Biden ($100-$200k), showing that those who made less than Biden gave more than twice as much to charity. No matter how you do the analysis the result is the same: penury.
