Amateurs Often Outperform Professional "Experts"

When amateurs outperform professionals, there is something wrong with that profession. Two examples:
1. If ordinary people, with no medical training, could perform surgery in their kitchens with steak knives, and get results that were better than those of surgeons in hospital operating rooms, the whole medical profession would be discredited.

Yet it is common for ordinary parents, with no training in education, to homeschool their children and consistently produce better academic results than those of children educated by teachers with Master's degrees and in schools spending upwards of $10,000 a year per student-- which is to say, more than a million dollars to educate ten kids from K through 12.

Nevertheless, we continue to take seriously the pretensions of educators who fail to educate, but who put on airs of having "professional" expertise beyond the understanding of mere parents.
2. Central planners in the days of the Soviet Union had to set over 24 million prices. Nobody is capable of setting and changing 24 million prices in a way that will direct resources and output in an efficient manner.

For that, each of the 24 million prices would have to be weighed and set against each of the other 24 million prices. in order to provide incentives for resources to go where they were most in demand by producers and output to go where it was most in demand by consumers.

In a market economy, however, nobody has to take on such an impossible task. Each producer and each consumer need only be concerned with the relatively few prices relevant to their own decisions, with coordination of the economy being left to supply and demand.

In short, amateurs were able to outperform professionals in the economy because the amateurs did not take on tasks beyond the capability of any human being or any manageable group of human beings.a
