No matter how much money you make, human greed is never ending. What will you do with 600 crores business taking 100 crore salary? Eat off Golden plate and make comode of diamonds? All will leave this world in 6x3ft and take nothing them. Too much wealth accumulation is an endemic.
Just imagine the kid's misfortune who will inherit such wealth with no muscle to work. That is why after each generation if brave kings, the next generation got wasted.
