Actually, this is only one of many holes in the pro-amnesty argument.
It's called "technological innovation." It's how we we've been able to produce as much food as we do- even before the invading hordes of Mexicans decided to come to the USA illegally.
To say that there is no other solution, is to follow the liberal mentality.
My tagline explains this further.
As a capitalist you must realize that the free market controls the prices of wages, goods and services. If there were a cheaper way to pick crops it would be invented. The free market is actually at work when Mexicans cross the border to pick our crops. Please send your suggestions of cheaper technology to the farmers of America. As it is they are losing marketshare to Chili and South America.
Calling me a liberal only proves that you have no answer to the question.
