Re: They all want to marry doctors and dentists and millionaires…
Bro, you are taking survival of the fittest theory in a different way. Consider two cases; one where a disabled person or a less qualified gets a high rewarding emoloyment due to reservation and other where a girl marries an all-evil son of a political or economical influential person. In first case, the person is inferior to the demand of the job but bypasses more compitent ones. They can be called fit for the job because of the law of the land (to ensure equality) not the requirement of the job. In second case, the son is fit because of the vertue of his father. So a bodily weak, qualitatively inferior person can very well survive and even enjoy all pleasures of the earth. Koyal bird doesn’t make nest. Many species don’t select mating partner they just accept the one who is available or who comes for mating.
As far as human are considered, I think girls and parents think many things before marriage like happiness, stablity, caste, religion, reputation etc. We live in a materialistic world where happiness is often associated with materialistis comforts and pleasures. Doctors and such professions are high rewarding and are financially stable. Here in India, a government employee is preferred over an employee of a well known private company or a businessman because of the same reasons. Having said this, there are also other factors which people here consider like caste, religion, social standard, reputation, safety.
