Hmmm....
Two points:
1) In the throwaway society that is the US these days, I'd suggest simply making a new model every three-four years is better than making zillions of the same antiquated model. But it's true that we (the US, again) replaces rather than fixes in many cases.
2) When legislation designed to protect everyone turns out to be expensive enough that it becomes a measurable barrier to entry into business and/or markets, then the larger companies will dominate, crush (in business or politically), or buy up those brave souls who fight the now regimented, legislated system. Not hard to predict at all.
