$6k/day for a person of LHL status doesn't seems to be a lot.
Last time when I went to cbd 1 financial trading office for interview, the interviewer told me he makes 5 digit per day and he asked me to look out the glass panel in his room, those guys outside (all with suits and jackets) easily make near 5 digit per day.
I didn't believed him yet until he showed me the money by dipping into his left pocket and grabbed out a folded stack of thousand and hundred dollar notes (appearing to be some sua lui aka disposable money)which I Estimated to be at least 20k. So I kind of believed him.
