President Obama’s jobs program calls for cuts in both sides of the payroll tax. That tax finances Social Security and Medicare. Social Security and Medicare are already taking in less money than they need to pay retirees. So they will have to cash in more of the Treasury IOUs left behind when previous surpluses were used to finance general expenditures. But the Treasury is also already running a trillion-dollar-plus deficit. So it will have to borrow more in the capital markets in order to pay back the Social Security and Medicare funds. Unless Obama makes up the lost revenue by changing the tax code. But then money will be withdrawn from the economy in the form of higher taxes so it can be put back into the economy through the payroll-tax cut. Somehow that’s supposed to stimulate the economy.

Got all that? There’ll be a quiz later.
