RANT: Why is every kids' sport SO EXPENSIVE?

Just signed my kids up for soccer this fall. Registration: $150 each. Then they need shin guards, cleats, socks. A decent pair of soccer cleats for a 7yo is like $70. And apparently we need to volunteer for three games or pay an extra $50. This is getting ridiculous. Single income household here and I feel like I'm nickeled and dimed constantly. Does anyone do sports on a budget or is this just the cost of being a parent in 2024?
