Christopher Garofalo spies another potential pile of money, ­writing:

“Presently there are about $5 trillion in individual retirement accounts. My suggestion would be a check off box on the federal tax return to designate a portion of required minimum distributions be used to fund construction, tax free for taxpayers.”

He also wonders if it would be possible for people to withdraw funds from retirement accounts before the mandated age of 70 to be used specifically for wall construction.

“It would be a WIN/WIN for the government and the taxpayer,” he writes. “A patriotic tax free gesture, minimum increase in the national debt and a possible bipartisan solution to a vexing problem.”
