I don't agree with your view, but I respect it. I can point out some facts though:
Bonera, 31 years old, signing an two year contract extension May this year:

Zaccardo, 31 years old, signing a three and a half years long contract this January:

This is only a couple of examples of Galliani's clownish behavior lately that doesn't make sense considering we're talking about two mediocre and more often than not unnecessary players.
Maldini has several times said that he wants to get involved in the club and the only one preventing that is Galliani. Ambrosini had to find out through media that Galliani didn't want to extend his contract. Moreover he was forced to hold a press conference by himself. Pirlo, however bad a year he had, was ousted by Allegri and was still better than other players that Galliani kept and extended contracts with. And he got a pen as thanks for all the years.
Our scouting system is so broke and it's because we don't really have any. Galliani just goes to one of his friends begging or he checks around if there is any players on bad terms with his employer and that's our transfer market.
It's beyond ridiculous to sign a back up striker for a back up striker for 12m, thereby financing Juve's Tevez signing. Even if it wasn't Adriano's idea, just the fact that Galliani went with it because a coach that has only 1 year left in his seat wanted him is facepalm worthy.
Well, that was a given when we allowed Allegri to still be a coach after all the horrible performances. We're not even aiming for CL qualification any more, just hoping that we don't end in Serie B next season.
