kpop vocal coaches seem to be about as useful as a cramp during a marathon

I just take it as racism at this point that people seem to think kpop idols are uniquely bad at singing. Kpop idols have to always be fantastic performers, superb dancers, write their own lyrics, produce their own songs, and have the most stable live vocals for every performance or else they are shit. That is literally the standard. I never see western artists held to this standard.
