You need to run the numbers...we would need economic growth in excess of eight percent per year, without a break for 30+ years, to cure the SS/Medicare deficits.
Ain't gonna happen, and I'm sick and tired of using "growth" as a way of pandering to the "don't cut MY benefits" crowd.
My personal idea for solving the Medicare and Soc Sec problems is something like a "Medicare lien". When the amount you've taken out of the system exceeds what you've paid in (with a reasonable allowance for compounded interest) the government gets a claim on your estate for any additional money paid to you or spent on your medical care.
I question your numbers for one particular reason: when taxes are cut significantly, the resulting economic growth will be exponential, not linear.
This distinction is critical to understanding the potential to solve our economic crisis.
But the greatest obstacle to overcome is the resistance from the permanent political class, who oppose tax cuts because (despite the fact that tax cuts bring more money to government) they represent a transfer of power from the government back to individuals.
