I fear for the future. Many 'career women' aren't interested in having
children, so who is going to be producing the kids to pay our pensions

I caught a comedy film the other day called "Idiocracy" with hit on
exactly the same theory.

It suggested that responsible, cautious and intelligent couples delayed
parenthood until financial security and stability had been achieved.
Conception was less successful, which resulted in a higher proportion of
intelligent families going childless and the eventual loss of parents
with responsible values.

Meanwhile, the lazy, stupid, unemployed trailer-trash produced lots of
rowdy and uncontrollable children early in life which did likewise,
resulting in the gradual down-turn of the overall IQ of the world.

It has some very funny sketches in it at the expense of the terminally
dense and pulls a lot from the traits of the yoof of today. Particularly
the language, where they couldn't understand English anymore. I can't
help but think there's a serious message and a nightmare vision that
might come true one day...

I have to say though there is no sign the two killed in this incident
were of this breed - more it appears to have been an addiction to this
kind of activity.
