Unfollowing and not paying attention is easier said than done. There's tons of people who post brag posts about anything on social media all day. Many of us would have very little friends if we unfollowed everybody who did that.
I agree that I think most folks who have their kids in hockey these days could afford to send them to Canada for a week long skills camp. Most people who aren't high earners or really into hockey never considered putting their kids in hockey in the first place. I know one mom who said they couldn't afford a hockey academy tuition but they seems to easily afford out of state and country teams/tournaments.
Unfollowing is very easy. Delete Instagram, Facebook, Twitter from your phone and live your life not others. So by your comments you have no friends if you don't have social media? So you would lose friends in real life not pretend social media life?
Don't unfollow people, just quit social media. You will be much happier unless you replace the need for constant info streams with the news media. Then you should just #rope. There is a great big world out there worth enjoying that doesn't involve other people's daily lives streaming into your eyeballs all day long and every day.
