What if the main goal of every pokemon game wasn't to become the champion, but to become the battle facility head?
All the other battle facilities: Complete all the challenges and beat the other heads! Ah ha! You have won against me! Congratulations you are now in charge of running this facility!
The Battle Subway: Beat the battle Subway, go home, complete Highschool, apply for college, complete College-oops,didn't get the appropriate degree?-Go back to college, complete college again, apply at the subway, get the lowest rank job, train your caboose off, slowly move up the ranks, finally apply for the subway master position, hope you are qualified enough, realize this job is 60% paperwork, 45% Trains, 5% pokemon, Wonder why ten year old you couldn't just try to become champion instead. Cry when the current subway bosses kick your *ss. Go home and think about your life.
All this to say that I bet Palmer over in Sinnoh doesn't even have a GED.
