Giant version of high school soccer? Kookoo you must have been smoking something. Look at the rosters from the teams. They are loaded for the most part with the top players from the club teams.
My dear Zizou, it's an analogy. Inter vs. World Cup champs, Inter would probably win, but only if Inter kept overlapping players from the WC champs on their roster. e.g if Brazil wins the WC, then Inter would retain Maicon, Lucio and Cesar et al. Now, do the same thing with a high school team state champ and the state champ of the club teams. See how that works?
