Are People Becoming Overspecialized?

When I was driving home from my father's house one day, I heard a commercial for a service in the local area (which includes the town where I grew up) called "Captain Laundry". The commercial started with a couple devolving rather rapidly into a screaming match over who would do the laundry, because neither of them had any time to do it. "Captain Laundry" kindly makes itself available to come to your house and do your laundry and dry-cleaning for you, so you don't have to worry about it.

This rather irritating commercial got me thinking about the concept of comparative advantage: in economic theory, nations will supposedly specialize in those areas where they can produce more value than other nations. I wonder if this idea has started to permeate individual lives, as well.

There seems to be an increasing tendency to think that all of our actions have opportunity costs that are measured in real income. If you are better at one thing than at all other things, you should devote almost all of your time to doing that thing, because you will be able to make more money doing that. Since you command a premium in that one activity, you can then afford to pay someone else to do all the stuff you are slightly less good at, but in which they excel. Economically, everyone wins, because they get to demand the highest price for their time.

Does anyone else see this as being increasingly true? If so, do you think it is healthy for the human mind to be transformed into a one-dimensional task handler? Do we lose something of ourselves by devoting what is fundamentally a generalist intelligence and skill set to an increasingly limited scope of activities?
