TIRADE: The cost of kids activities is INSANE

Okay rant incoming. Between soccer, swim lessons, and piano I'm spending like $600/month on my two kids' activities. MONTHLY. And that's after I said no to robotics club. My wife and I make decent money but this is legitimately cutting into our budget. I'm not against my kids doing stuff, I'm against the fact that a 6-week swim class costs $150 now. When did everything get so expensive? And everyone acts like if you DON'T do a bunch of activities your kid is gonna end up behind somehow. I feel like I'm just hemorrhaging money every month.
