I think you have to start from the destination.
What do we want football to be?
I could write about ways to make it be competitive and have 3/4/5 way title, European and relegation battles, regularly rotating which teams are at the top and winning beyond “the top 4” but I feel like I’d get 20 comments from people who don’t want that and the whole thing would get derailed like the first post.
If you do want that then you have to narrow the gap between richest and poorest somehow, which means changing the revenue distribution, I’d definitely bring back ticket rev sharing because it would get rid of the arms race to exploit fans (5% ticket increase is less attractive when half is going to the other teams). Then you have to address the CL money problem, you’re always going to get a top 4 when 4th gets £60m extra a year to defend that position against 5th.
The ideas are easy, the difficulty is that you’re trying to bring in a system that benefits the poorer smaller players in the sport and hurts the big players by taking away their advantages.
