I also find that fewer people are able to fix them.
Having been taking my cars to a friend's shop for 20 years. I see him turning away business more often because his young techs aren't as good as the old ones, there's A LOT more for them to learn, and the old guys are retiring.
The Stealership must not give them a very good percentage of the $200-250 labor charge or they'd have an incentive to learn the ropes.
Look on Facebook marketplace and you will see a lot of 250,000 mile cars for sale. I just gave a 2001 Expedition to a friend that had 189,000 on it that ran like a clock. There are plenty of Toyotas on the road with 200,000 on the odometer. When I first started driving we ignore cars with over 20,000 because we figure they were about ready for a valve job, which in those days could cost you 50 or 60 dollars.
