Yes, FIFA hasn't done anything for the countries whose football is developing today. That's the result of clubs investing their resources in scouting or building academies, which are very helpful in developing talent. And then it's also the result of their governments constantly striving to improve the quality of their leagues and enable these players to compete better and develop their talents. As for FIFA, what they do is not much, especially since FIFA is the most bureaucratic, non-transparent, and overly political sports organization, so there's not much to expect from this organization.
No sporting body in the world right now is perfect. And I would say that FIFA is far better when compared to other sports organizations such as the ICC. In cricket, rather than trying to expand the sport, the ICC is trying really hard to restrict the sport to the 12 "full members". 89% of the ICC revenue goes to just 12 full member nations (with 40% of all the revenues going to just one country), while the 96 remaining ICC members get just 11%. At least in FIFA, they have a very unbiased system to distribute the funds.
