Perhaps people go into the trades _because_ they are expensive to hire.
The market works two ways.
Well, job pay seems to be based on status anyway. Switzerland is ridiculously rich either way.
Aren't many of these trades very very heavily regulated? I'm not sure how much of a market you have there in the first place.
Given the option, people don't flock to low paying jobs, so the market works both ways. If you want to have a good pool of good workers you have to pay accordingly.
I'm not sure why you're being downvoted. It's a legit question.
Because we've all heard the "market" arguments hundreds of times here and they never seem to have much to do with reality at all. It's gotten to the point where I have real trouble assuming good faith when someone brings it up again.
Switzerland is known for high fixed cost of living. It has been said that the Swiss people don't place higher value on "lesser" tasks, so it makes complete sense that it is expensive without any relation to how much the market is saturated - it wouldn't become cheap even if the market was oversaturated, rather some people would go away from that market - because of fixed costs of living.
