As mentioned here many times before, that $66 doesn't cover your time getting to the game, the time checking the teams in, your fuel costs getting to the games, the 30 minutes in between games, the report you have to write up if there is a red card, the drive home, the fuel cost driving home, the gear you have to buy, the certification costs, which are substantial, to say nothing of the other benefits you would need to cover for your self like health insurance. If you are lucky enough to be assigned 3 CR solo spots back-to-back-to back at the same facility (the very best case scenario) your $198 will cost you almost 6 hours, so you're making $33/hour minus your expenses. And for all your trouble, you still get to provide your own health insurance and have lunatic parents scream at you while you're trying to do your job. $100K per year? Come on....
Its pretty much voluntary work, for refs with a day job, who earn a decent living, file taxes jointly, the games which are not cash on field, you are paying at least 50% taxes state and federal, minus costs, knocking yourself out for pretty much zero money.
So your choice is
-Kids 13-18 who don't have much experience at the game, or life. Struggling to manage the people side of a game, new to it. If they are any good, o once they get any good, they will move on
-Older refs who are doing it, essentially for free, to help the kids, or for exercise, and can do a decent job
-Over 60's , retirees, not as nimble as they once were, as mentioned
I think the middle demographic are the most desirable?
20 somethings with the necessary experience won't be doing kids games. They will have moved on to older players.
If a 30-55 year old ref, who has a decent job Mon-Fri is doing it, parents should be incredibly grateful because
a) they aren't doing it for the money,
b) they are the most likely to be good at it, of the population you are getting for kids games
c) they put up with a ton of hassle and abuse no matter how well they do
d) they are giving up their weekends and may well be missing out on time with their own children, or even their own children's games
e) Refereeing is not easy
If you are earning 100k+ during the week which a lot of parents in SoCal have to, otherwise they wouldn't be able to live there, $66 for giving up your Saturday morning isn't really the point, its a trivial amount of money, especially after costs (also not mentioned above by Topeswin is the fees taken by the assignors and the apps used for assigning games)
