Conde Naste’s Portfolio Magazine has compiled a list of billionaires ranked by their charitable donations. The Generosity Index itemizes fifty of the wealthiest individuals as donors, relative to their wealth.

Coming in fiftieth is the miserly media mogul, Rupert Murdoch. It shouldn’t surprise anyone that an uber-conservative, Republican monopolist, should finish last in expressions of charity. The Republican me-first ideology that values greedy self-centrism predictably drives people like Murdoch to the bottom of these lists.

At the other end of the spectrum, the top five most generous billionaires (Warren Buffett, Bill Gates, Eli Broad, George Soros, and John Kluge) are all reliable supporters of Democrats and most have contributed to the campaign of Barack Obama.

This news bite is just a little more evidence that Republicans tend to be selfish, social Darwinians and Democrats tend to have more compassion and concern for the well being of others.
