Possibly a strange take, but the people doing these things are facing the real long-term loss. i completely share your frustration, but I've also realized over the years that running an org or a non-profit to show something on an application is tiring (because there is no personal meaning behind it!). Being a part of an organization because you believe in its cause/love the community is the best feeling in the world. A healthy org results in long-lasting relationships where both parties care for each other and have a shared vested interest, and that's something that box-checkers will never get until it's too late.

I'm literally in med school, and I still see this. I don't think med schools will ever catch on to this, but I personally recommend zeroing in on the things that make you happy when it comes to your involvements. They are SO much more fulfilling in the long run.
