Today's Wall Street Journal has a great line from former Treasury Secretary Lawrence Summers. I'll quote the Journal's Capital column on page A2.
If the distribution of income in the U.S. today were the same as it was in 1979, and the U.S. had enjoyed the same growth, the bottom 80 percent would have about $670 billion more, or about $8000 per family a year. The top 1 percent would have about $670 billion less, or about $500,000 a family.
The obvious remedy to this problem of a poor distribution of wealth is to increase taxes on the top 1 percent of families by about $500,000 (don't worry, they won't miss it and they can afford it) and cut taxes on the bottom 8 percent by $8,000 per year.
