ski racing is fun, and I still find the time to enter a race every season, if not two.  Some racers do get cocky, like they own the mountain, but I think a lot of freeskiers do too.  A lot of racers ski other places too, i.e. park, pow. . etc. . ..   I raced for like 5 years and enjoyed it.
ski racers are also going to be better skiers than non-racers.  This is not even debatable.
there are so many aspects of skiing to choose from, I suggest just skiing how you want, and enjoying other people around you.  If you are respectful and friendly, chances are, they will be too.
NOW, if we are talking about racing coaches, yes, they do sometimes seem like they own the mountain.  I have had problems with my own coaches in this aspect.  But it is not all of them either, I know a lot of super cool race coaches who just dig skiing.  they like going fast and chasing gates, and I would never knock on someone for that.
If it wasnt for ski racing, we probably wouldnt have skiing as we know it. Think about how many of the pros used to race?  ESPECIALLY the pioneering pros.  McConkey, Morrison. . .  most all of them have a racing background.
