In reality, NICA demographics would need a solid 20 years of data to say with any certainty. And even then, so many other factors will play into any case study.
From an anecdotal point of view...
1. You do shit with your kids when they are young
2. They get older, and don't want to do said shit with you anymore
3. Then they go to college and no shit gets done, because beer
4. They graduate and get jobs, real money, and they eat more good food
5. Then they get fat
6. Then they look for an activity to help them be less fat, see "do shit" statement from item 1
All you can do is plant the seed. NICA is currently planting a shit-ton of seeds in the environment. Will these grow in time? Logically it would follow. But in reality, it'll take years for us to see what grows from that.
I mean the alternative is that we can cancel NICA and spin up a Burger King & Video Games league.
