The percentages you asked for are: The top 1% had an income increase of 281% since 1979 and the top 20% had an increase of 95% which was less than inflation. Those in the bottom 80% made less.
Yes its true that 60% of the richest Americans made it on their own but that doesnt mean much when you actually read what RGR wrote. The income of the top 1% represented 23% of total income in 2009 and it was 10% from 1950 till1980, 15% in 1990.
Calling someone a moron doesnt make them wrong it just holds you to a higher standard of intelligence which you clearly cannot afford. If you are not smarter than he is then I guess you have to be an idiot or an imbecile.
