waynet, you must realize that the money in investments has already been taxed when earned originally! the low tax rate on investments is what keeps people investing and our economy healthy...this is not a good idea and will not pass, but is being used to sound good to those who don't fully understand the difference between earned income and investment income.
as for mr buffet, i believe he already is fighting owing millions in back taxes, so he is a fine one to stand up for this!
