Privileged does not mean that your life is perfect, it means there are things you never experience and bc of this you are privileged over those who do. The inequality is structural,
privilege is backed by institutional power. There are many characteristics that intersect in this theory - it's called
intersectionality.
Unfortunately, Moonbin was going through stuff that us looking on the outside could not and did not see. It is unfortunate that his life brought him to this decision, but I hope he is in a better place.
Being a kpop star is just a job, they are not the center of this industry - we don't see most of the people involved.
There's a lot of pressure when you're a public figure and everyone's hyperfocused on your looks and performance: I'm sure he was worried about ageing, noticed his body getting weaker - same as athletes. They still have performance reviews, bosses, managers, who often are unbearable and dishonest.
The "normal" was different for him, he did not struggle for necessities anymore, but it created other problems - no anonymity, the press looking for scandals, disingenuous users, even antis and stalkers. You might dislike being a product others invest in expecting to turn a profit, Knetz are not the kindest consumers either. Idols often complain about loneliness, depression, anxiety.
It's obvious that fame and money don't change this world, everything stays ugly, awareness will still crush you. You will get ridiculed for ageing and eventually end up forgotten. It's delusional to idealize this lifestyle.
Maybe he decided to leave when he was at his best, that industry is brutal and demanding - we're part of it and we consumed him.
Whatever the reason, he was still very brave to make this decision for himself. It's the real salvation to be rid of this place.
