A strong border and harsh stance on illegals sounds great on paper.

The problem is that doing it would cripple our economy. I'm not even understating the problem.

To just say "be tough on illegals!" is to make the same mistake most liberal thinkers do on damn near everything. They look at a problem and craft a grade school, wafer thin solution without considering the reprecussions fully.

Many US businesses would be forced out of business or made to leave the country entirely if suddenly they had to hire a domestic workforce (and pay them minimum wage plus benefits.) The US would lose jobs, and costs for everything would skyrocket.
