Dear Larry:

My apologies for getting back to you with a delay.  It is OPEN ENROLLMENT
season and I am thinking of changing my University of California health
plan.  I am sure you and some others on this list have had the pleasure of
dealing with comparing health plans and deciding which one will "fit" your
needs and ability to pay.  What a delightful experience is health care
market--so transparent to all "economic agents."

Thank you very much for your considered response to my inquiry.  One thing
we can take away from it.  This is an opinion piece written for an American
daily--admittedly with a more sophisticated reader.  If you (a chemist) and
I (a lay person with advanced degrees and some science background) cannot
"weigh in" it poses a problem for Science for the People--how can we make
expert decision making tangible for the public if the public should weigh
in on policy aspects of the problem at hand?  With scientific and
technological paste of development and subs-specialization would there ever
be a bottom-up democratically run society?  Of course, the problem is not
limited to science--it extends to all kinds of fields of knowledge.  Can
there be a true democratic society in a highly complex society?

Best regards,

Kamran
