Thats kind of a surprising and provocative post!
I guess its never a nice reminder that desperate want to be parents can really be reduced down to their core element of being the prospective $$$ that keep the "fertility business" turning!
My view is that infertility and the absolute fundamental urge, drive and desire and motivation to have children - which is an awesome and dreadful obstacle to face in life - would actually be dampened by difficult economic times

- though I suppose it makes it all the more heartbreaking and difficult for those of us who might be directly affected through economic downturn (like losing your house or job!).
Many woman and families already put themselves into almost destitute situations to put themselves through IVF and try and build families - particularily where funding is tight (where isn't it!) and incur huge debts whilst foregoing the other advances in life like home ownership that our peer groups indulge in.
Am sure fertility clinics will probably be one of the last bastions of business to see a slow down - as I doubt most infertile couples view having children as a luxury good (like a holiday or car or nice new fridge) that they could forgoe. So I guess kind of like bread milk and petrol (you know - lifes other essentials!) business will weather the change about as well as any other core essential life service!
The $$$ coming through the doors of fertility clinics in 12 months time might prove me wrong on all that of course.
