It really doesn’t sound like the original OP wants to be rich, though. As far as I can tell, their fantasy is to be a regular school kid (obviously Japan being the baseline, on account of including that anime pic and no one in the west (consciously) watching Korean or Chinese anime). I suppose an upper middle class kid in Philippines, Indonesia etc. is probably similar enough to satisfy anon’s fantasy. But I think especially in Korea and China, you would actually still be expected to work your ass off in school even if you’re rich.
