That's because of the cheap material used in the blocks, etc.
I have taken cars in on trade from OLD ladies who never revved it beyond 3K rpm. Yet NONE ever came back for snapping rings when some kid bought it from us. (Former Ford employee). Why? Because the blocks are a lot better (or the cylinder liners, car dependent), and don't wear so readily. No "ridges" of import are formed on them to snap rings like older cars developed, which is why you used to be told that if a car had been babied for 50K miles or whatever, never un-baby it or it will die like a dog.
