Steven Den Beste Strawman

having read this article - found that there is a definite planet
bias in it - what is an economy - just a way to have some make more
money than others - in a space society there should be enough
resources to allow all to have basic needs met - ( home, food,
clothing, etc.). In reference to age, on the planet people retire
(basically mandatory ) to allow the younger generations to have
work. there is no reason to do so in space where there may not be
enough people - get older and take over other jobs that do not
require large physical inputs ( many professionals who have such
jobs work well after 65 - doctors, botanists, people who just love
what they are doing). Another assumption is that there is only one
colony - with multiple colonies you can have some migration of
people and their skills so the assumption that you have to be
pigeonholed rings false.
On earth many isolated communities survive quite well without
massive inputs (most inputs are not needs but wants anyways)
and as for infrastructure you are starting with a plan - you can
build the capability of infrastucture ahead of time ( no need to dig
up main street for that subway) so that rings ignorant -
how is that for a start?
