At the same time, earnings in the agricultural sector will also likely improve (not only might labour productivity rise as a result of applications of modem science and technology to farming, but so would demand for farm produce). And with generally better education and health services for the agricultural sector as well, birth rates may fall in rural as well as urban areas, reducing the rate of growth of the labour force. Eventually, a point will be reached when income distribution improves. This is essentially the reason which led Kuznets (1955) to advance the now well-known inverse-U hypothesis between income inequality and economic growth.
