Tax the cash and marketable securities assets of major corporations to pay down the mountain of federal debt

Tax at a rate of 100% the cash and marketable securities (excluding from this tax a total equal to 3 times annual revenues) held by major corporations earning over $500M/year in revenues. The big corporations out there are sitting on a pile of cash and that money came from this nation's citizens' pocketbooks. It's only fair that the fat cat big corporations should help out at this difficult time when our federal debt has gone over $16T, and that's why the millionaires and billionaires should also pay 50% or even 60% rates for their income taxes. After we clean up our nation's balance sheet, we could cut back the tax rate on the wealthy and not tax corporate cash and marketable securities again. Then, we can solve the problems that our current tax revenues ought be solving.
