CBO has interesting data on the growing income gap in a report this month.
Some figures from one chart on the
average after tax income over the last 25+ years (
pdf)
the lowest fifth increased from $14,900 to $16,500 from 1979 to 1986 - 11% increase
the second fifth increased from $30,100 to 35,400 from '79 to '86 - 18% increase
the top fifth increased from $98,900 to $184,400 from '79 to '86 - 87% increase
the top 1% increased from $337,100 to $1,200,300 - 256% increase
Pretty much explains why I support a progressive income tax....and I still aspire to the top tier...even if it means paying a higher percentage marginal tax rate. (not that I expect to make that top 1%)
