Just being honest here.....younger people aren't interested in officiating game because of attitudes and spectator belidgerance, IMO. Oofficiating is a difficult job. Different rules per organization, small but different and sometimes hard to keep track of. You have so much to keep track of, pitches, balls, strikes, runners leaving early, feet on the rubber, legal equipment, anticipation of what could/should happen but focusing on what is happening and so much more.
It isn't easy and frankly the way "fans" and coaches act many, many times makes it a thankless job. Fans complaining about calls, spouting rules they know nothing about, entitlement of coaches/players/organizations/fans and absolute disdain people show officials, even so far as threats and physical attacks on them.
Now ask yourself if YOU want to be the "Blue" and put up with all the non-sense while officiating a kids game....oh wait, I mean the championship of the World Series. It's a thankless job for the most part, that's why those that accept the fact that officials aren't perfect, WILL make a mistake, play on to overcome those mistakes and shake hands after the game, say "good game Blue" or say thanks make you want to come back tomorrow!
Thats the biggest reason people don't want to officiate anymore...tired of the abuse AND let's be honest we aren't raising generations of kids any longer who have tough enough skin to tolerate all of the above!
As always, my $0.02.
