I think that there are three problems, I'll try to give parts of solutions.
1- Big clubs missing from Serie A or not competing
We must have Juve, Napoli, Genoa back in A, and Fiorentia, Milan and, to a lesser extent, Parma staying in A. Having the best clubs in the first division is just instrumental for the credibilty of the competition. If a top team demotes every once in a while because of financial problems or corruption scandals, you can't expect TV channels, investors, players and foreign fans to show real interest in Serie A, can you?
2- Security and comfort in the stadiums
Our own Delle Alpi is a mess. I've been there and enjoyed it, but you can't compare it with the German, Spanish, English or even Dutch stadiums. Seriously. If Serie A is totally behind the rest of Europe on one matter, it's definitely the stadiums.
Fan violence is a big issue too. Clubs are very scared of their own Ultras and often prefer not to act against them. A specialised police system is needed. And racism and fascism must be banned asap from every Italian stadium. Di Canio's salutes were more broadcasted on foreign TV's than Sheva's goals I'm afraid.
3- The development of Italian youth
Italy might be World Champion, but didn't it strike you that the youth doesn't seem to follow. I mean, we've been looking for a young Italian DC for ages, and the only good one seems to be Barzagli. Nowadays, some tip Criscito, but none of them are world class for the moment I fear. And apart of them, who can find good young Italian DC's? It's not only about DC's. I went through the Azzurini list, and apart from Andreolli, none of them is playing at a high level yet. Young players shouldn't be rushed, but you could expect at least 4-5 players in that list to play regularly in a good club in the top league. I mean, have a look:
Goalkeepers: Gianluca Curci (AS Roma), Daniele Padelli (FC Crotone).
Defenders: Marco Andreolli (FC Internazionale Milano), Michele Canini (Cagliari Calcio), Domenico Criscito (Genoa 1893), Lino Marzoratti (Empoli FC), Marco Motta (Udinese Calcio), Francesco Pisano (Cagliari Calcio).
Midfielders: Ignazio Abate (Modena FC), Simone Bentivoglio (Modena FC), Paolo De Ceglie (Juventus), Raffaele De Martino (Udinese Calcio), Marino Defendi (Atalanta BC), Claudio Marchisio (Juventus), Valerio Virga (AS Roma).
Forwards: Arturo Lupoli (Derby County FC), Michele Paolucci (Ascoli Calcio 1898), Gabriele Paonessa (Vicenza Calcio), Nicola Pozzi (Empoli FC), Andrea Russotto (Treviso FC).
Deschamps and Blanc said we would go for youth, but I fear we'll have to invest in foreign youth, and might look like Arsenal in 3 years...

Solutions?
1- Big clubs missing from Serie A or not competing
I'd see two complementary solutions:
a) Reform the FIGC, as today it's clearly too dependent of some clubs who'll just fool around when they want it. Not only the members have to be nominated more objectively, but the whole system (including the FIGC tribunals) has to be changed and be more transparent. Did someone seriously understand something in this summer's procedures? I know I didn't, and I'm a Law student...
But, Carlo already said that in La Meglio Gioventu. He dreams of moving to scandinavia because there, states are like glasshouses, everyone can see what's inside,... unlike in Italy.
So I have to admit I don't have big hopes on this one.
b) A yearly financial control on clubs. In Belgium, clubs have to get a yearly licence to play in professional football (First two leagues). This happens with a strict control of the clubs finances and situation. It's not a problem for big clubs, but small clubs have been relegated to 3rd division.
It has some advantages: 1. A year-to-year sight of the clubs' situations. 2. Clubs won't go bankrupt in the middle of the season. 3. The players will be paid on time, the most simple remedy against player bribing.
2- Security and comfort in the stadiums
a) English fans might be known as having the most violent, stupid, drunk hooligans, you have to agree that in 10 years the violence inside the stadiums has drastically decreased. Stadium banning, more police control, clubs controlling their own fans,... lead to this situation. The Italians might learn some lessons there.
I really like the traditional Italian system of Ultras, it adds something to the myth, but some of them have really nothing to do in a stadium. Extreme-right flags or chants should be banned immediately, and yes that also includes Juventus fans.
b) The stadiums are crumbling. Which club in Italy has a great stadium? Rome's Olimpico is crumbling, Delle Alpi is a mess, will we ever go back there?, San Siro was good in its time but looks stone-age when compared to, say the Allianz ArenA.
Blanc hinted everything would depend on EURO 2012. That's a long time to wait, and what if Italy doesn't get it (which is very likely)? Wait another ten years? Juventus was the only club who had a project for a new modern stadium but we can forget it since our relegation...
3- The development of Italian youth
While playing FM, one thing struck me: the Reserve's haven't got a competition. Spain lets the Reserve teams play untill the Second division, other countries have reserve competition of their own.
Oh yes there is the Primavera. Let's be serious. The Primavera is good for players until 18 years of age. After that, there's no point in letting a 19 year old kid playing a duel against a 16 year old. The older one will get bored, and will not progress anymore.
So what do we do nowadays? We send them on loan. Far from our top youth-coaches and accomodation. In their new clubs, they are litterally used. The clubs take everything out of the young players, and when the return, they usually have the ankles of my grandfather or the knees of Mathusalem (the biblical figure, not the player).
Basically, their top career is over when they are 22. And I fear a player like Volpato is heading that way.
Why do we let our youngsters being destroyed by some Serie C1 relegation battlers? To let them play competition, and against more experienced players.
Well damn, it doesn't take a rocket scientist to see the obvious solution: Give them competition football inside our club.
How? Split Serie B into two groups, with each of it half of real teams, and half SerieA reserve teams.
The reserve teams would be made of 1. The best youngsters. 2. Out of favour experienced players. 3. Top players looking for match fitness.
That way we could see how the youngsters play at a real football level, and play them against rough experienced players; and in the same time, have them monitored and trained by our own coaches and physios.
Mourinho has called for that in England, Anderlecht's Vercauteren did the same in Belgium; it already exists (succesfully) in Spain and to some extent in Germany. So it's everything but unrealistic.
