Jeff G. at Protein Wisdom ("because not just anybody can summarize the news") has a good handle on the nature of the problem.
Money quote(s):
"I understand that we can’t deport the more than 12 million illegals already in this country; but we shouldn’t reward them with a “path to citizenship” either. Secure the border. Then let the illegals decide what they want to do once we make it clear that we will not be granting any amnesty to lawbreakers. Period.
If these people are living scared in the shadows, there’s a reason for that: they are here illegally. And with real unemployment and underemployment already at close to 20% in this country, the last thing we need to do is flood the labor market with millions of legal, unskilled laborers.
You want to talk to me about increasing guest worker programs? Fine. But in the meantime, we need to be cracking down on employers who take advantage of illegal labor — in conjunction with releasing these same employers from growth-choking taxation and the kinds of ridiculous and redundant regulatory burdens that drive up the cost of doing business to begin with."
Nothing dramatic. Simply enforce the laws that are already on the books.
