There is a glaring fallacy in your post.
Simple put, growing government is akin to the drunk who tries to keep from tipping over by attempting to run faster and faster.
I hate to keep stepping on the clay feet of your political diety (I really don't) but the vaunted FDR did just that with Social Security:
The Social Security plan was that workers would pay for retirees, and, based on actuarial tables, those who died earlier than expected would add to the fund.
a. No one considered that life expectancy would increase?
b. No one considered that the balance of workers and retirees might change?
c. No one calculated the long-term costs?
d. Ida May Fuller, the first person to begin receiving benefits, in January, 1940, when she was 65- she lived to be 100. “…worked for three years under the Social Security program. The accumulated taxes on her salary during those three years was a total of $24.75. Her initial monthly check was $22.54. During her lifetime she collected a total of $22,888.92 in Social Security benefits.”

e. “Social Security will pay out more this year than it gets in payroll taxes, marking the first time since the program will be in the red since it was overhauled in 1983, according to the annual authoritative report released Thursday by the program's actuary.”

f. “…redeeming trust fund assets until reserves are exhausted in 2037, at which point tax income would be sufficient to pay about 75 percent of scheduled benefits through 2084.”

Wasn't this the economics whiz you suggested was "infallible"?
