Obama, Taxes, and Fairness

From William McGurn at the Wall Street Journal:
For Obama, Taxes Are About Fairness

McGurn presents some good analysis about the Saddleback Church debate, and concludes with a good followup question:

Mr. Warren, a man of the cloth, has done us a great service by asking the candidates to answer a pretty secular question: What kind of income makes an American "rich"? Maybe in the more secular setting of an upcoming debate, one of our nonpastor moderators could ask the candidates the moral question: What specific rate of individual taxation would it take for the rich to be paying their fair share?

I don't know how John McCain or Barack Obama Jr. would answer this question. However, Barack Obama's father, Barack Obama Sr. has given us his opinion:

Theoretically, there is nothing that can stop the government from taxing 100% of income so long as the people get benefits from the government commensurate with their income which is taxed. ( http://www.ibdeditorials.com/IBDArticles.aspx?id=302137342405551 )

Note: One of Obama's two autobiographies was title Dreams from My Father. Apparently, Obama's dad was dreaming of a whole lotta taxes.
