Why do all k-pop artists need slave training lol?

K-POP is korea's and most of asia's widely marketable form of entertainment. Now, think of any group, think of your favorite group or your most hated group, or both, it doesnt matter. now think of what that group would be like and how different they would be, had they met via school, or friends. and naturally became successful entirely on their own drive. i know that big bang writes their own music but g dragon still needed years of training at the hands of some mastermind, not of his own mind. justin bieber just had to post some vids on youtube lol! thats just the american way i guess. it just saddens me to see all the(mostly girls) posting questions on korean entertainment company auditions. it shouldnt have to be like that... if u have talent, you dont need to feel desperate at the hands of an indomitable system. cuz u think JyP is going to change anything about his way anytime soon? lol better get an account on youtube lol. unless youd like to be a slave, which is fine, to each their own!
