Housewife

Feminist may argue that my blog yesterday had a discrimination against housewife and claimed that this important group does not contribute to the economy.

Not at all. (It is obviously a division of labor; without someone taking care of the dinner and laundry and children, how could the working husbands focus on their job ?)

Nonetheless, we could learn from Adam Smith that only there exists only limited number of methods for a society to provide material for the subsistence of its people: labor, product of the land, rent and profit. (I shall not go through their definitions here.)

And, if you consider the economy system of the whole society, housewives do not "earn money" as such.

You comprehend the problem now ? With the same consideration, doctors and nurses are no different from housewives in terms of the country's economy: We do not earn money (unless, of course, you profess at taking care of tourists and foreigners).

The inevitable conclusion is: any increase in lifespan would translate to an exponential rise in the number of personnel we need for medical (and, more importantly, nursing and other routine) care, and therefore the number of mouths need to be fed by each working class person.
