I don't know about others, but I'm perfectly fine with a part of my tax-money going to other people having some fun, relaxing sex without having to worry about unwanted pregnancies and STDs (why-ever anyone would want a STD... :-P).
This Earth is dangerously overpopulated, we're close to procreating ourselves into extinction. Which would probably be a good thing for the Earth.
However, we do NOT need to worry about lack of population.
Sure, we do not have eight or twelve kids anymore, as they had before the enlightenment, but most kids born today survive their fifth birthday, which only about half of the kids born during the Dark Ages did. Few people then lived to see their fiftieth birthday. Nowadays, almost all countries have an average length of life longer than fifty.
A bit of googling later:Eight countries have lower average length of life than 50 years.
Zimbabwe, South Africa, Guinea-Bissau, Swaziland, Chad, Nigeria, Afghanistan and Angola.
For those who are uncertain about Geography; all of those, except Afghanistan, are in Africa. Afghanistan has had an ongoing war for the last, oh, 40 years or so, which might explain some of it.
Most of the ones between 50 and 60 years average, are also on the African continent.
The top is not nearly as "monochrome", there are countries from all over the world, mostly Europe and Asia. Canada is on 12th place, Sweden's on 16th place and the US on 50th. The first African country is on 58th place (if I haven't missed any); Libya.
