Should poor people be sterilised? If we sterilised the bottom 90 percent of the country (in terms of education and economic background) and allowed only the top 10 percent to reproduce, by the time the entirety of that 90 percent dies out, India would literally become a first world country. There would be greater competition for white collar jobs, and only deserving people would get these jobs, while the rest (like our brainlet "engineers" who can't write a line of code) would have to settle for blue collar jobs.
We would have to build state-funded old age homes for those of the 90 percent who have no remaining children. The cost would be enormous. But the rewards would be equally great. There would be no poverty left in the nation. गरीब हटाओ, गरीबी अपने आप हट जाएगी।
The new population of the country would be about 130 million, with a similar population density as Tunisia. This is more than enough people we need in one country.
