Not exactly sure what you are saying but Michigan State and Washington both made the CFP within the first three years and their programs didn't seem to benefit at all. In fact , their programs seems to crater in the years following their CFP appearance.
The system has been in place since the beginning of college football. Each team has 85 scholarships but there is no player draft so the talent acquisition is hugely one-sided in favor of the programs with years and years of history, tradition and deep pockets. And the new rules only make the discrepancies between the have's and the have not's, time will tell. Now, trying to deal with 19-year old millionaires who have no real responsibilities will be tough and might backfire, we will see. But this era isn't any better or worse than any other era in terms of equity and inclusion, it's just in the past National Championships were given to teams that in some cases didn't even play a Top 7-8 team (or in BYU's case, a Top 20 team I believe), much less beat them.
