It's how migrant families (including my own) always have been here. They have always been willing to put in more, even when they clearly are aware they are being taken advantaged of (by the American standards, of course). I am 1st generation, and I can tell you right now, I would never work 13 hour days every week for years on end without a vacation like my father did. And that's a good thing, of course. But again, my comment was intended to be an observation more than anything.
