Something tells me if we had the foresight to see what problem we were creating when we followed the "experts" advice and taught our kids to think for themselves and not to always follow the "rules" that everyone else sets for them, maybe we would have raised them differently. It's one thing to teach your kids to be independent and not to just follow what the crowd is doing. Now we've got a generation that thinks they can pick and choose which rules they follow, including guidelines for pace of play.
I really, really do not want to get into an off-topic debate over generation gaps or stereotypes per generation. However, I can assure you that this generation also has many intelligent and independent youths who can decipher right from wrong and are equipped with common sense. Please, let's not forget that the acid-dropping generation prior to ours is what got us into a whole economical mess to begin with, while it is the younger generation and their future children that will be living in the consequential mess.
On the topic of golf though - Again, you cannot fix stupid, period. This has nothing to do with parenting or generations/generalizations of golfers. This is purely a common sense issue and those who have no common sense may never have that awakening moment when they realize that they are a part/cause of an issue that is affecting those around them. Another issue is that another small percentage of those who DO wake up and realize they are slow golfers will probably not try to do anything to fix it, but yet they will continue at their pace and maybe let you play through after 3-5 holes of suffering.
In the end, there's no one solution that will satisfy the masses. You either strictly enforce a Pace-of-Play structure on the course which starts with changes implemented from management down, or you loosely remind golfers that they should be aware of their pace. There's no grey area or perfect solution here.
