The main companies going out of business would be those that rely on illegal aliens and cheap labor to make their faulty business models profitable. I really don't care. Some of the businesses that were driven out by the people who obtained an advantage by breaking the law would probably reappear.
And as far as rising prices, are you trying to frighten me with expensive lettuce? About 10% of the cost of lettuce is attributable to labor. That means that you could double the cost of labor and the labor cost on a $1 head of lettuce would rise from 10 cents to 20 cents and the price in the store might rise to a $1.10. I dare say I would save that extra dime on my medical insurance premiums when the hospital emergency rooms quit cost shifting all the indigent care to insured customers.
Illegals make up about 3% of our population. A lot of them are children that cost us money but don't work. They are at the very bottom of our economy so they (labor plus consumption) can't account for more than 1 to 2% of our GDP particularly since about $50 billion of their earnings get sent out of the country as remittances and don't recirculate in our economy. Our GDP grows at about 3% to 4% annually so do the math. A bona-fide recession requires 3 quarters of shrinking GDP. Losing the economic contribution of all the illegals would barely qualify as a real recession. We'd grow it all back in nine months. Its a price I'd pay to be rid of them.
Well said.
