Well,look at Manchester City,look at Chelsea before and after Abramovich,R.Madrid with Perez...
When you have an unlimited resources you can buy enough good/great players that it's impossible to compete against.
Barca is just an anomaly,it's not a standard...having a home grown generation of Messi/Xavi/Iniesta/Puyol/Valdez/Pique/Busquets/Pedro/Thiago is not just rarity it's unheard of in European football.
Without us,Madrid would dance through La Liga and the Champions League and they're the definition of a bought team.
