How does it matter if there is still enough demand for these goods to be sold out? Remember prices are controlled by the government for basic necessities such as these.
> Let me ask you, why you think India is overpopulated?
How is this relevant to overpopulation being or not being a problem?
Looking at population density of India, I don't think it's population issue. You mentioned overpopulation in your response to India's problem. I assure you, India can grow as rich as US even at 3 billion population.
India has many problems but population at present in not one of those, maybe it will become a problem if population growth is kept uncheck. But don't blame slow development in past and present to population.
Population being accumulated in few cities is a problem of government and their failure to understand how market works and how they can better it.
None of the political party in India have any viable development plan.
>If the population of India halved over night, there would be half as many mouths to feed; there would be much less unemployment people could afford to charge higher wages for unskilled jobs (because there would be less competition to drive prices down.) How would that not be an improvement?
There will also be less demand for goods, ask those countries which have negative population replacement rate. Where will the demand come from if population halved that means half as much demand for your wheat, rice, and all other necessities.
