So let's use your math and say that 65% of the MSU fan base is made up of people who make 60K-70K/year. That's probably 35-40K people. If you can get those people to give $50/month, which is a drop in the hat, that's 21 million-24 million dollars in NIL. If you only asked for $25/month that's still 10.5 million-12 million.
So it actually can come from middle income folks. No one is asking you to give 5-10K/year to NIL. Just give $50/month. If you get enough people doing it, then it makes a difference. This isn't rocket science.
