curwin,
I think I know what you are getting at. I myself have often wondered what drives people to do the jobs that they have. You know, what drives someone to be a high rise construction worker, or a doctor, etc… I myself wanted to be a doctor once, until I realized that I would be a bad one since I have a natural dislike of people in general. In the technical sense, I’d probably be a great one, but if you don’t like people, there’s sort of a conflict of interest with the Hypocratic oath and all… blah blah blah, anyway…
As far as what the economy needs, that already exists to a certain point. If there is no demand, there is no hiring. If there is a demand, people work towards it, perhaps not so much out of love for the job but the job itself. Remember a few years back when the IT explosion began and everyone was trying to become a computer expert? Not that everyone loved puters, but that was where the job/money/security was at the moment. Now, the market is kind of flooded but there is a shortage of nurses, so there’s a lot of people working towards becoming an R.N. There’s a bit of a time lag in it all, but it does kind of work in a supply and demand type of thing.
As far as people doing what they are good at… it’s a roll of the dice. Some people are very talented in certain areas, but do not really enjoy the work. Only a true professional can do a job that they dislike, and only then for a certain amount of time. People simply have to be able to do what they enjoy to be happy.
As far as the scenario of an island, I’ve thought of the same thing, as I’ve mentioned. “How does a group of people figure out who does what”? If you have a group of people that are all doctors, or have a natural talent for being doctors and nothing else… forget it… you won’t last too long. But I think that generally, you will find a good mix of talent and desires among a randomly selected group. As I’ve mentioned, I enjoy woodworking and am very good at it, but I don’t understand how some people can actually enjoy construction jobs for a living and take great pride in it. I know I couldn’t do it. Yet some people don’t care if they hate their job, they are all about the money. All people are different, and between personal preference and general job markets, it usually works out okay all things considered.
Just some ramblings of a guy on cold medication, advil PM, and booze.
