The problem with a broke league like Serie A is the smaller clubs are directly or indirectly, too dependent on the Juve's and the Inter's of this world. The moment the big teams go into a slump financially, the rest of the league crumbles as well. Lack of funds within the big teams would mean a poorer product, less appeal and ultimately leading to less TV rights money which clubs like Atalanta are benefitting off currently.
And these small teams don't step up. They're happy with their comfort zone 'safe haven' of finishing in the top 6, collect their prize money, sell their best players to the highest bidder, rinse and repeat. This is what Agnelli meant when he said the situation has been the same for 80 years.
If you are suggesting that Juve's and Inter's are creating a disparity in Serie A with the ESL then I would counter it by saying having a broke Juve or Inter would lead to an even worse product of Serie A.
Besides, the main catchment area of the big 3 is... Serie A ofcourse. That ESL money will directly go towards funding transfers from the smaller sides.
I know I may be trying to paint a positive picture but I wouldn't jump to conclusions just yet. I want to see what structure they have planned when they talk about the 'football pyramid' before overreacting that they're 'killing' football.
