@sf111 I admit I don’t have any idea how it works in your country (I assume US) and I have no idea what those numbers mean (it’s hard to get a perspective on value when you’re that removed from that reality), but I also don’t want to shame anyone for their economic situation, I live in a poor country after all so you learn how to do things for the least cost, since you don’t have money to begin with. Don’t know how much of it is applicable all the way down in North America.
Community centres, be they secular or religious, are a great way to find cheap or even free classes and courses. Music ones are specially common, but also sports, arts, etc. They tend to fill in quite quickly so you have to be fast.
Some activities are more efficient when you take into account how much you spend on them. Don’t know how much 100 USD a week is worth for you, maybe it’s something your son really enjoys, but maybe a gym membership he could spend 1h every other day would be more useful in the fight against screens.
And, well, if you want to weaponise the enemy against itself, there’s free courses online for literally everything. Mathematics, physics, music, languages, arts, coding. Turn idle brain rotting screen time into productive, brain stimulating screen time.
