There is a clear divide between underdog and oligarch in college football. At the end of the day, they’re labeled. You’re either Power 5 or Group of 5. It’s have’s and have not’s. Those with money, and those without, and it benefits those with to keep those without hungry.
Money is the real divide. Those with money have had longer traditions of success. They’ve built large fan bases with parents passing a love of a team down to their children. More people want to see these teams, so they make more money from TV contracts, ticket sales, merchandise, and advertisements.
