when incomes are higher, living standards are higher and working the same amount gets u more money, what else does it mean???
compare pakistani street sweeper salary to american.
pakistani engineer to american.
pakistani doctor to american.
compare what a pakistani begger makes to american
Then see the difference...
In simplest words, money flows quicker in west, so u have better chance of getting some of it. Mathematically that translates to on average more money made per unit time worked.
Social benefits like supply of electricity, water and access to other public services increases living standards, so u have to work less harder....
