There was an argument to be had at some point, that more money going into football would improve the spectacle and experience for the fans. Better, bigger and safer stadia. More TV coverage. Top class training facilities for players, better academies and scouting systems. Et cetera. We're way past that point. If the last 10-15 years are any example the investment in these things has kind of levelled. More money going into football now mostly means bigger player salaries and agent fees, more expensive transfers and more corporate greed to milk the product.
More fans globally, but also more disenfranchised local fans about how things are going. More expensive tickets, yet less local fan emphasis since the tickets are now a tiny slice of the financial pie. Revolving door managers, prima donna footballers with little club pride or respect, owners of dubious origins and intentions, tosser agents making fortunes behaving like cnuts etc.
I don't think it's more money that's needed, but if there is to be more money I think it needs better spreading. What would make sense is to perhaps increase the squad size to 30 players and play more games. Enforce player rest quotas, to avoid overworking of star players. Which would also introduce a strategic aspect to the game, choosing when to rest which players. Create and market new competitions and move those competitions abroad to satiate the appetite. Use the enlarged squad size to spread the extra load.
More games for all fans, more round the year football, more money, more players to spread the money to. But don't reduce the offering to the local fans who have been supporting the clubs financially and physically for most of their lives. Don't take away the competitions they've been attending for years. That's not on.
