8mil people, 80mil people, 800mil people all can sleep until natural wake up. thats why i say no difference.
i never say poor people in my comparison. but end of the day, poor people work hard, need wake up early, may end up live longer than them... so earning so much may mean they can live longer than poor people. although it may extend their life expectancy.
if people see open, no comparison, actually all life are equal. feel content is the most impt thing. if rich, i feel they should contribute back to the society and help other people do meaningful things.
