Take The Pill, Bruce!

Bruce Kasting over at ZeroHedge (a financial-professionals website) takes a look at the numbers on bogus Social Security numbers and payments to "undocumented workers," and gapes.

He's not quite willing to take the red pill, though:

It's tempting to look at these comparisons and reach a conclusion that America could move the needle on unemployment by eliminating undocumented workers. As a practical matter I don't think that is possible, nor would it be desirable.

(His emphasis.)  Why not?
