Arizona lawmakers have wrongly and unnecessarily injected themselves into the illegal immigration fight by proposing a law that would revoke the state licenses and permits of employers who hire people in this country illegally.

A lack of jobs is one way to discourage illegal migration. But singling out Arizona employers for sanctions wouldn't make much of a dent. Migrants would simply travel to other states to find work.

It already is against the law for employers to hire illegal immigrants. However, enforcement of those laws should be left to the federal government - as spelled out in the Constitution - instead of establishing a hodgepodge of overlapping state laws.

This is a national problem that calls for a unified national solution.

The Arizona Legislature has plenty of state problems to address without getting into the federal government's realm.
