Dividends are paid to people that already own stock. If more people buy stock it is likely that they will buy it from other people not companies. Unless companies have been using large amount of cash reserves to buy back stock(some have) not taxing dividends has dick to do with corporate profits and reinvestment.
I say if I have to pay my graduated income tax with 100% of my income you should pay your 7.5 payroll tax to 100% of your income. (it all goes to the general fund anyway and is eagerly awaited by tax and spenders) Fair taxation on all income.
thanx,
