Why do soccer referees always seem so egrigiously bad?

I've always been kind of a fringe soccer fan, but over the last few years I've been getting more and more into it. By into it, I mean I watch National Team games, and huge European games. Every game I watch, the referees always play such a huge role because of some horrible call/non call that is egregiously fricking wrong. They're so bad it's like they're just trying to piss people off, they seem so absolutely clueless...like the ref in a WWE match that pretends not to see a tag team member hand the other guy a steel chair, then gets turned around, and misses the good guy get crushed with the chair. Referees/umpires/officials are all guilty of bad calls, I get that, but are all soccer referees/games like this? It's fricking infuriating.
