"In simple terms, the 1% are sitting on tons of money but are not investing it in creating jobs because there is no demand for goods and services because the 99% have little money to spare for new products."

You are either ignorant, or choose to ignore the facts.

1.  If the 99% have no money it is because all the corporate taxes imposed on the "wealthy" are being payed by the middle class because the wealthy do not pay taxes, they pass it on in higher prices, lower wages, or lay-off's as explained here before.  And you want to tax them even more.  Anyone who thinks the wealthy will pay more taxes is a fool.  All taxes trickle down and trickle up to the middle class.

Just an inquiry about the hypothetical situation which you've presented.

If the 1% have the ability to increase prices to offset any increase in taxes as you say, what prevents them from increasing them now (without any increase in taxes) and increasing their wealth even more?

"what prevents them from increasing them now"

One of the big restraints on price is competition.  There are others. 

But, they will maintain their ROI, regardless.  The only alternative is to go out of business and invest in something else.

They can reduce their ROI.   They can reduce some big salaries and bonuses.   They can be more efficient.  

Those are other alternatives.

 
Wouldn't that price competition be equal in restraining them from increasing their prices for both adding to their wealth and paying a few more per cent in taxes?

Why do you claim they apply in one case and not the other?
