From a piece a few weeks back that I hope Karl Rove read:

There’s little question that the demise of the summer job is due in part to globalization. For one thing, with millions of low-skilled immigrants around, service industries don’t need to rely on kid labor the way they used to. Lawn-care companies and fast-food restaurants can now employ a more permanent adult staff. And, according to Neil Howe, an expert on age cohorts, kids are so used to seeing immigrants doing that sort of work that they assume “I don’t have to mess with food or cleaning stuff up.” Ironically, the same kids whose parents are paying $4,000 for them to go to Oaxaca to build houses for the poor can’t imagine working for money next to Mexican immigrants at the local Dunkin’ Donuts.

Of course, this isn’t really a question of globalization but rather a discretionary federal program called immigration.
