I love Hans Rosling's talks (not to mention the pretty graphs).
He's definitely not a primitivist though. I bet he wants to smack everyone claiming to be a primitivist.
A recurring theme in his talks though, is that many poor people (almost the definition of 3rd world) have large families and high infant mortality.
Actually a recurring theme in his talks is that for much of what we still call the "3rd world" that is no longer true.
(This is tangentially relevant to the argument about leisure time as referenced by Mr. Rosling).
He wasn't talking about leisure time, but rather time spend more productively, on education and self-improvement, while also having fun.
I washed all of my clothes by hand for about 18 months. Not fun, but I would gladly trade that for having to sit in traffic, etc.
I don't think washing by hand or machine and having to sit in traffic are in any way related. I never have to "sit in traffic" as I walk everywhere, but I do have a washing machine. I love that thing, and everything that made it possible.
I think that basic hygiene and germ theory have probably been more helpful from a "number of lives saved" analysis than cutting edge diagnostic techniques, but your point is noted.
I quite agree. I even used this point to challenge Beerina in one of his healthcare rants in which he claims that the improvement of medical technology exponentially increases the number of lives saved. I've shown that much of the great lifesaving improvements in medicine occurred during the sixties and seventies, and that since the eighties there is only a very slow improvement in lifespan (which I suspect is mostly due to safer cars and better traffic management).
That does not however mean that I think the improvements in medical technology have been unimportant. If you suffer from a potentially lethal medical problem 1970s medical technology would probably have saved your life, but it would have diagnosed your problem very late, you would have needed to stay in the hospital for many months and get out with huge painful scars. 1990s medical technology may not save very many more lives, but the lives that it saves are going to ruined a lot less: the problem may be detected much earlier, and keyhole surgery can solve it much quicker and with less scarring. I think that's a modern achievement not a lot of people would want to trade in for a more primitive life.
Some of the improvement in life span were indeed caused by basic hygiene and germ theory, particularly the improvement in the late 1800/early 1900s when average lifespan in the West jumped above 50. It is not an argument in favour of primitivism though; the jump was caused by the construction of city wide steam powered sewage systems, drinking water systems and government hygiene campaigns. In other words: modernism.
