I’m going to explain that using Maslow’s Hierarchy of Needs.
“It’s quite true that man lives by bread alone- when there is no bread. But, what happens to man’s desires when there is plenty of bread and when his belly is chronically filled?
At once other (and “higher”) needs emerge and these, rather than physiological hunger, dominate the organism. And, when these, in turn, are satisfied, again new (and still “higher”) needs emerge and so on. This is what we mean by saying that the basic human needs are organized into a hierarchy of relative prepotency.”
That was the inference derived from extensive research by renowned American psychologist Abraham Maslow who described how man always strives to meet new needs every time s/he has achieved what they earlier wanted.
The first stage of these needs refer to physiological needs like food, water, warmth et cetera. The second stage refers to need for provisions and systems of safety and security. Then comes belongingness related needs in the society. And, this goes on this way.
Infrastructure plays a pivotal in an individual’s life in fulfilling those needs at different aforementioned stages. Infrastructure here refers to building up of a sustainable ecosystem where one’s extant needs turn into a reality.
Infrastructure makes possible for any particular need of an individual to be fulfilled. And, thus it is quite natural that a person would also strive to locate themselves into geographical locations where pertinent infrastructural resources are in place to provide for one’s needs.
And, since well qualified and educated teachers are bound to have needs reaching up to the higher stages, they too seek and strive to teach in the schools and colleges of areas where the relevant infrastructure is already in place.
Alas, most of the rural hinterlands, tribal areas and remote villages of India aren’t yet are equipped with infrastructure to even support the needs of the basic stages, let alone the higher needs.
And, that drives away the well-qualified teachers from moving to such areas to disseminate their knowledge and enlighten the lives of those hapless children in whose life even a little exposure to education could usher a new zeal and energy to better their lives, their surroundings and contribute better to the world that is presently devoid of their potential.
And, therefore there is an urgent need for infrastructural push in the rural and tribal areas to incentivize the teachers to move from their urban bases and expand the reach of our knowledge economy.
