even in poverty countries, there's signs of progress. Deaths of
  infants has gone down worldwide in EVERY country dramatically
  since 1972. There's an amazing graphic showing that I could
  find. That's the majority reason why populations have grown so
  much. Our average death-times have changed but not THAT
  dramatically. In the USA, making $34,000/yr puts a person in the
  top 1% of the world. I still love that little statistic; puts
  things into a good perspective. ==
