why do rich countries spend millions on anti depressants medicines???

We could apply Maslow's theory in this case. That is, each of us is motivated by need. We start with the most obvious needs of survival (food, shelter, water, etc.). As each level of needs is satisfied, we seek gratification at the next level. The five levels are (1) air, food, drink, sleep, etc.; (2) security, protection, law and order; (3) love, family, relationships, work groups; (4) esteem, reputation, responsibility; (5)personal growth and fulfillment. The majority of the population in third world countries is still at or below the poverty level so their people are still struggling with levels 1 and 2 in the hierarchy of needs. Countries like the US have a majority of the population struggling with levels 3 and above.

when you have money your supposed to be happy but you'll have a bigger problem on how to spend it and how to make a profit from it. that's why anti-depressants are made for :P

may be that people of such countries are having the broblem of dippression a lot
