What would be better is if they can work together to root out the corruption, but as long as profitability is worshiped as openly as it is, it will tough to fight since money is so concentrated and it's now a kind of self-sustaining entity.
Other confederations are important for FIFA-internal politics (especially the African votes, Infantino's biggest group of supporters), but for fans and players the quality of the clubs matters far more. And that is geographically clustered
On the field, Brazil doesn’t appear to be most important these days.
Fewer than Argentina.
Fewer than Uruguay.
And yes, I acknowledge your cherry-picking was Libradores.
Brazil has the richest league in South America and thus like England its teams can buy better players.
The fundamental problem with FIFA is the revenue body is also the sport’s standards and adjudication body. Split those functions, with one selling tickets and divvying up spoils, while a separate committee polices the sport, and you put aside a lot of the corruption issues unique to FIFA.
FIFA has a billions in revenue and reserves. Many of the supranational areas are developing and need that income support, at least it looks like outreach, even if it's bribery-shaped. Even in developed nations the people who make the decisions have long tenures and like paid lunches and free tickets. Tough one to crack.
UEFA is upset about FIFA’s finances because it cuts into UEFA’s finances.
I mean UEFA hasn’t put forward ethically superior plans to finance Futbol development in the poorest parts of Africa, remote Oceania, or tiny Caribean islands.
Indeed, in recent years UEFA has expanded UEFA competitive fixtures to increase revenues via 1. The Nations League, 2. The UEFA Conference League, and 3. The League Phase format of the Champions League and UEFA League.
Each of these is at the expense of countries outside of Europe via reduced opportunities for international friendlies witheuropean clubs, increased club calendars and associated injuries (player injuries have a disproportionate effect on countries with shallower talent pools).
All the UEFA complaints about the expanded world cup (and club world cup) were regarding actions UEFA has pursued in recent years…including the money grab.
If you have to bet, bet its the money not the principle of it.
