Yes. But do they make waiting lists of 5-10 years? When I say "quality control," I don't literally mean "quality," in the sense of finely refined luxury goods -- not sure why you took that meaning from my comment. I mean what you refer to above -- being hands-on in the process and being unable to relinquish your baby. A 10 year waiting list (maybe not for shoes, but other crafts) creates undue scarcity even when the item is not luxurious -- simply a big bottleneck of unfulfilled orders. That's oftentimes just a failure to scale because of myopic need to have oversight over everything. I'm not necessarily knocking it, I'm something of a control freak myself, but it's an unfortunate situation for the consumer. That being said... I believe the consumer is partially to blame for this, given the effects of herd shopping behavior and buy-in.
I'll give you a stupid but salient example: waiting for 2-3 hours to try the "latest" bowl of inexpensive soup/cake/donut at a store that has two employees and seats for four people. The wait time is completely out of proportion to the experience, but there is a powerful herd mentality at work. The proprietor fails to capitalize on the opportunity by scaling accordingly and the (sane) consumer misses out by not being willing to wait 2-3 hours.
Paradoxically, precisely because of this herd mentality, the long waiting list may be a side effect of flash-in-the-pan buy-in by a particular type of domestic consumer that (let's be honest) is extremely sensitive to newness and group behavior. When that group migrates, it might be up in smoke. Those that scale and create a more reasonable and sustainable turn around cycle can nurture a lifelong customer base. So your examples of the 4-6 man teams above would be good examples, and I'm sure they will stand the test of time in what is already an oversaturated market. The Sartoria Corcos of the world, which fail to widen the bottleneck, I'm not sure those will be left standing after the current consumer tires of really small suits and moves on.
