To use a motoring analogy, you are claiming only those who buy kit-cars and assemble them themselves are proper motorists - unlike those "halfwits" (as you so delicately put it) who buy a ready-made car from a dealer because all they have to do is turn a key & drive off.
"..PC ownership is wholly and significantly much, much, much greater than Apple ownership.." Probably so - but then going back to my motoring analogy, Vauxhall Nova ownership is wholly and significantly much, much, much greater than Jaguar/Ferrarri/Bentley ownership - proving what, exactly?
I don't think the OP would be best pleased to hear his kids described (inaccurately & unfairly) as dumb, any more than I would be delighted to hear my wife described as dumb simply because she drives (and drives very well) but she would not be able to balance twin SU carbs, change the &*^%£$ bypass hose on an original Mini or retime an engine with a strobe lamp.
Most people today want something they can just use without getting their hands (metaphorically) dirty. Just as the days of the sought-after Chauffeur/Mechanic have passed, many of us who do delve inside the box of our computers are finding our talents to be unnecessary, and yes - it's a blow to our egos to find we no longer have the almost hero-worship we enjoyed some years ago, but that's progress. Ranting about it doesn't and won't help.
I switched focus to Macs in the late 1980's for that very reason - I realised that the techie knowledge I had acquired & used since the 1970's was on its way to becoming no longer needed.
My Grandad used to tinker with his car in the 1920's at least every week - frequently more often - just to keep it going. Me? I just take ours to the dealer every 12,000 miles, and I only check the consumables (oil, water, tyres etc.) every weekend.
On the Mac? I just back up the HDs and little else. I can do whatever might be needed should it ever be necessary, but I haven't had to do much else for many years of ownership from my LC to my current MacPro.
You want to travel a different path? That's fine by me and I wouldn't revile you for doing so.
However, I WOULD revile you for heaping execrable invective upon someone else and his family for having the temerity to entertain a point of view not wholly in accordance with yours.
