Control the border, pay more?

"People have dual interests," says Jared Bernstein, an economist speaking about the immigration reform debate now before Congress. "Ask them, do you want your lawn to be mowed as cheaply as possible? They'll say yes. Ask if they want to control the border. They'll say yes. Ask them if controlling the borders means they're willing to pay more for lawn care, they'll say how much? And that's what we're going to find out."
