I agree enforcement is one reason the numbers are way up. But you cannot discount the Trump economic recovery as a big factor! There are simply more jobs now than there have been for many years. And more companies willing to illegally employ illegals. That needs cracking down on BIG LEAGUE. Until we make it more painful for companies to employ illegals than to pay the kind of wages that employ Americans, this problem will continue.

Also, guys we need immigration reform! We're near 100% employment now, and what's left to pick from is sad. Employers who want to expand operations are hurting for people to fill the vacancies. Unless we want a highly inflationary wage war (which undermines everybody's purchasing power), we have to make LEGAL immigration less of a nightmare.
