Couple of points. The reason we aren't throwing money around is not because of Wilders philosophy, otherwise we would be buying young upcoming players from higher leagues as well. It's because we don't have the money, pure and simple.
We ARE fortunate that Chris Wilder and Alan Knill are capable - more than capable - of working under such conditions and can spot players in lower leagues. To suggest that this is actually the "plan" when it's forced on them by necessity is ludicrous. When people worry about Wilder leaving to go to a club who will give him money to spend, do they think he'll still only shop in the lower leagues and not spend big money?
The way we play is not unique to us. Many Spanish teams play exactly the same way. I was flicking between four Italian games yesterday. The Genoa game was untypical, blood and thunder, hoof and all out attacking from both sides. The other three, which included AC Milan, every team played how we try too.
Wilders plan is about signing the best players he can, gelling them into a good hardworking side to be successful. The fact that it's United, will be more in his heart than his head, which is where his decisions come from. It's football, not a Disney film.
