Yes, we all wish we could turn the clock back. There are companies out there trying to make a difference with training for young people. The industry is not dead, I can look around at many on £30K, £40K, £50K, £60K salaries and above driving nice cars, enjoying their work and thanking their training (if they are really honest) for their situation.
I can also look not too far and find someone bitter and twisted with an axe to grind, if I look hard enough.
You sound like a good guy, don't bother getting bitter like some, get your act together, look further afield and open your eyes and ears. Keep positive.
I'm beginning to get used to your 'i's.
