Immigration and Wages

David Frum has some interesting points here about the role of immigration for Romney and Perry:

Perry’s views on immigration are not a “liberal” deviation from his views on the minimum wage, on Social Security, on healthcare coverage, etc. His high-immigration views are of a piece with his general preference for a low-cost, low-wage economy.

By contrast, Mitt Romney has begun to articulate a call for a high-wage economy. To get average wages rising again after a dozen years first of stagnation, then of outright decline, will not be easy. The most important step is to control healthcare costs. The rising cost of healthcare benefits devours workers’ cash pay.

But a rethink of immigration policies is also necessary. In the September 7 debate, Romney articulated something almost never said in a Republican primary: much, much, much more important than a fence or “boots on the ground” is tighter enforcement of labor laws inside the country. I’d go further: if the labor laws were effectively enforced, a border fence would be a costly redundance.
