Man, the big picture is really lost on you guys.
No it's not. Your big picture is basically an absolute best case scenario for us that ignores all the RISKS involved with our rivals strengthening which at the very, very basic level include us missing out on one of the limited CL spots in our league.
Would I love to be the best team in the best league in the world with billions of dollars in revenue? Sure. But I like where we are right now, building slowly and steadily, owning our own stadium, increasing global appeal (with which winning helps btw). We are already experiencing the benefits of dominating our league: For example, Tevez taking a pay cut and Llorente waiting 6 months to join us.
You, and many others, are caught reminiscing about the past incarnations of the Serie A and the footballing world in general. Nowadays, you can get as much TV revenue as you want but if you don't have an Oil Sheik for an owner, you will lose out more often than not when chasing a top player.
Then it becomes a question of what are the other more responsible methods to accrue top players and your answer will be the youth ranks. Establishing a monopoly on our domestic talents whether they are Italian or not can only be seen as a good thing and we are experiencing the benefits right now with Pogba and soon Berardi.
If I can exchange our ability to compete with spending 40/50/60M on one top player for the rights to vacuum up all the top youngsters in the nation like Bayern does, then I will choose that path because it will ultimately lead to an extremely formidable team, capable of CL success and world wide following which will only churn out higher revenue.
