Views like this are incredibly short sighted the game would be lost in many smaller countries without international football. Many smaller less well off nations wouldn't even be able keep game going at even a basic level with out the money generated from competitions like World Cup, Euros, AFCON etc.
Besides most players love playing for their country plus internationals attract huge audiences a significant amount of whom will only be casual followers of the sport but whom still generate significant revenues for national associations. A lot of the money is invested in grass route football. Most countries do not have huge football clubs with a global reach so the role of the national association in developing talent becomes more important.
Do you think a lot of the money is filtering down to grassroots football in all of these countries?
Experience suggests 'small' countries and larger richer countries football associations have a long record of siphoning off money very effectively.
Maybe a pause from all the desperately shit international football (even the proper tournaments have been majority poor in the last 10 years) might allow some thinking space to come up with a more sustainable and high quality model for investing in grassroots football that doesn't involve running a countries few high quality players into the ground before they're 25
