They're not really smarter, just more practical and cohesive. Asians will work together as a family and a community to advance themselves. Also, they fully believe in working harder at getting an education. Most anyways. Vietnamese can be the rednecks of the Asian world. The one's I've worked with in the welding industry tend to use crack, waste money on gambling and other stupid things. They were always coming to me with sob stories of losing all their money at the casino and can I help. Nope. Some of the worst worked on shrimping boats. They'd get off the boat, hang out an hour or so then get itchy feet and wind up at a casino or bar and come back a day later broke and frustrated. I'd laugh at them and tell them to next time drop off half their cash with me and then come back after the rest is gone. I'd take care of them and budget their funds until it was time to leave port again. None of them ever took me up on the offer.
