The Following Is a Comment to the Article "Are Jobs

Essay

The following is a comment to the article "Are jobs obsolete?" by Douglas Rushkoff, Special to CNN September 7, 2011 (http://goo.gl/0aUXL):
Karaya: "We are at the point where the growth of human population becomes liability rather than asset. Higher sustainable standards of living can be maintained with much less population, and population growth actually can lead to humankind decline - just by depletion of environmental resources alone."
Karaya's comment implies that lower population would actually increase standards of living due to advances in technology. What do theories of growth have to say about the effect of population increase on economic prosperity? Is there a connection between a country's population, its technology, and its standard of living? What kind of information would you need to try to answer this question? How would an answer to this question look like?
