I've noticed that certain ethnic groups seem drawn to particular industries. A few examples are:
The Arabs seem to have a corner on the gasoline industry. Go to any gas station, and chances are, a nice Middle Eastern fellow owns it.
The Indians (from India) seem to be drawn to the car rental and hotel industries. Go to any hotel/motel or car rental location, and chances are, someone named Patel owns it.
Here in LA, go to any char-broiled hamburger fasty food joint (not Burger King), and it will be run by a Greek family.
Also, here in CA, it seems that every Casino is run by a Native American Indian
Although this is no longer prevelant, back in the days when rubbish collectors were small outfits, all of them were owned by Russians.
Go to a delicatessan. It is almost guaranteed that an Italian will own it.
Why is that? What draws certain groups of people to certain occupations? What are some others besides the ones I mentioned above?
