Maybe it's just me but it sounds like metal workers and fabricators in the US are greedy as hell.
No it's universally that way among industrialized nations of wealth and middle class.
I suspect you could even find a lot of high pricing in China.
I was working on a custom case 5~ years ago for mini form factor boards and lots of them. I could find a local blue collar metal shop, but whole rails and up to DC level finish would be refinement and cost. Small things would add up.
At one point I contacted a company in the UK who had blueprints and designs online and had built and shipped units. A 4U unit, just the case $2600 USD. Needless to say, I scrapped that idea.
I find it routinely hard to find professional services for reasonable rates in most blue collar fields.
Heck I went looking for an auger motor a few weeks ago and the manufacturer doesn't deal with the public. I can contact the manufacturer of the device this goes in, but they will upcharge handsomely. So that, when I get to it is finding the master distributor / sales agent outsource person and find warehouse they stock such. But often, even that is a hassle, as those places don't sell to the public which then means back to the sales agent for another referral. Probably a $35 part that they'll end up squeezing $100+ out of me for.
I must have spent 2 weeks years back trying to find regional source for kevlar belts to a certain spec. Knew the model, manufacturer, etc. Horror finding someone that would sell to public. Had another similar experience with HVAC piping of all things.
It's a protection racket and the high prices are them often sizing up your wallet which I find insulting. Price should be similar for any five different people, not ad hoc justified by their perceived value of the collection of coins in your purse.
