Do We Need Illegals To Run the Economy?

Thomas Sowell reports:

What about all those illegal workers that we "need"? Many of the illegals are working in agriculture, producing crops that have been in chronic surplus for decades. These surplus crops are costing the American taxpayers billions of dollars in government storage costs and in the inflated prices created by deliberately keeping much of this agricultural output off the market.

Do we "need" illegal workers to produce bigger surpluses?

No we don't.
