The only reason we don't reform our work visa programs for cheap labor is because business owners do NOT want to have to pay these people minimum wage, pay taxes on them, or pay to insure them (workman's comp and similar). That's it. That's all there is to it.

As soon as you institute such a program businesses could get sued for illegal labor conditions, abuses of employees, sexual abuse of employees, violations of contract law, and more. Their expenses for imported labor would probably triple.

Would such businesses close as a result? Maybe a handful would but the real impact would be a huge drop in profits—also known as a greater share of profits going to workers.
