>> ... my $50 membership thirty years ago is worth $1,000,000 in 2010 dollars ...
All moot, of course. Your fifty bucks contributed years ago was exactly that - and nothing else - period. It was used back then - and any comparison to what it is worth today is valueless.
"What have you done for AMSAT recently?" - is a much more appropriate discussion.
