I have a feeling that quotas by continent are not based on the quality of national teams, but there are other reasons for this.
There is an obvious tendency for more and more national teams to participate in the World Cup, and for the World Cup to be held more often, even every two years.
The reasons for such decisions are not sporting but purely financial in nature.
Earnings are the most important for FIFA, not sports motives or the development of football, and they have been known for corruption for a very long time.
Attention, I agree with you. But the two things end up going together.
Which continent has the most countries with the best football quality? Europe.
On which continent do the best players in the world play? Europe.
What nationality are most of the world's great players? Most are from European countries.
Which continent will generate the most revenue in the football market? Europe.
That is, despite knowing that FIFA moves where the money is. It is also in Europe that you will find the best players, the best leagues and the best clubs in the world. In turn, those with the most good national teams.
Of course, the less investment there is in other continents, and the less projection players outside Europe have, the harder it will be for more countries to become great in the world of football.
