I only have 45 years on the clock, getting my licence in 1977.
My experience with hams has been contrary to yours, perhaps as most of those I know are either currently, or were employed in Electronics, many being ex-workmates of mine.
That said, one of the most prominent Amateurs (now SK), in microwave work in my State, with a number of distance records to his credit, was a medical practitioner.
I was "off the clock" in ham radio during my career. After I retired I got back into it around 2013. It lasted until this spring, when I disconnected my VHF/UHF radios and set them away in the closet. Couldn't take the bigotry, religious, political, and just plain stupid talk I was hearing. They have every right to speak it, but I also have every right to turn them off.
I still keep in touch with a few by phone, and one comes over here to check out my projects and to go eat at the local Thai restaurant for lunch. I remember the first time he came over. Not ever coming over (but meeting me at a ham sidewalk sale), he didn't know what to expect. He probably expected to see a basic ham equipment on a desk, but he was blown away with all the test instruments. This stuff is not what they have any experience with (and I don't expect them to).
I have fixed radios for a lot of people including him. Last year he had a DMR handy-talkie that he said was "dead" when he turned it on in the morning. He was exclaiming to everyone that "this thing is dead and there is no coming back to life for it! I'll just buy another one." I told him to wait why not let me check it out - what do you have to lose? He brought it over but didn't seem to think there was any chance to fix it. Long story short - it was a battery terminal on the PCB that wasn't designed very well and the screw wasn't making contact any longer with the PCB trace. It isn't something you could see you had to take a bunch of fiddly parts off. Let's just say he ate a little crow. I've also fixed radios with the simplest of problems. Why can't these people even try? They don't seem to even want to take the cover off and look inside.
Electronics projects? Nope. Other than putting up antennas they don't do projects or even kits. If they are doing them they sure don't say a word about it on the radio, yet they will speak any opinion about any possible subject. No, they will either send in a broken radio or buy a new one. There is only one other guy in the area that works on them.
There are very smart intelligent hams out there concerning electronics knowledge, I've never said there wasn't. But unfortunately my local group seems to be an "outlier".
I'll leave you with a picture I've shown before. A ham transceiver I had to bug-bomb before fixing. Why? Because it was full of little critters as delivered to me ... use your imagination.
That's enough.
