I think it's more of a scaled-down version of the Valdes situation. He's really not that good a keeper, but he's a much-better-than-average player of the ball than most goalies. That's what matters to Barcelona, and that's why he works well for them. His defense and his team try to keep him safe so he doesn't have to actually do that much goalkeeping, and he participates more than most goalkeepers in the flow of the team itself.
I believe that many of the La Liga teams have developed a similar style, but with nothing like the quality of Barcelona and Valdes, so when they come up against a strike-force the likes of Barca's, they just get ripped to shreds.
See, the thing is, I do watch La Liga. ;) Their games are won and lost in midfield, and right now, the greatest Spanish midfield of all time is concentrated in (nearly) one place.
It's that bottleneck of talent that causes the divide, and I think that's helped out a lot by the share of television rights. If that were more even, then sure, maybe the other teams would have a chance to hang onto their homegrown talent, instead of taking the money from their sales to cover their club debts. Lack of television revenue hurts these clubs hard. :/
