so now we are starting to get somewhere. It seems you think the bottlenecks are similar to the ones I flagged such as knowledge, discovery and certification. If you know a way to find the people starting that aren't charging 200/hr, please let me know because I want to hire them.
You can always try putting out an ad on Craigslist: "Need someone to fix my car (or landscape your yard or prune your tree, whichever thing you're trying to get done) for $X/hr. No experience or certification or warranty of any kind required, if you get hurt I guess I'm paying your medical bills, if you've never done this before now's your chance to muddle through and find out how on my dime, and if you ruin my prope…
You might have a point that everyone is so rich these days that they are willing to pay $200 an hour for a reputable plumber to unclog their toilet rather than take the risk it with a $50 plumber without 500 yelp reviews.
This would certainly explain the trouble young people seem to be having starting plumbing businesses and introducing some well needed competition.
I think this would fall under the discovery or triangulation problem.
