Well, most Americans do work and work pretty hard. Not compared to Asia, but compared to Europe, Americans work harder and longer and take off less time. Do we have an underclass that refuses to work? Yeah, but that's a minority. It's also why Mexicans are everywhere a job is available. I'm not an open borders guy, but it's easy to see why so many are working on construction sites and anywhere manual labor is needed.
It's also a sign of how well America's economy is really doing.
