The U.S. has the same problem. Now that people have lost faith in the "middle class society" and we realize that 99% of us are poors at the mercy of bosses and health insurance, the IQ 120+ set is deferring childcare until they "make it", the odds of which are very low and most people won't because even at 140+ most people get screwed. So smart people are self-selecting out of the gene pool, not with that intention but by deferral. It's a nasty boiled-frog problem. One day we will wake up and the world will be terminally stupid.
Now that the individual's economic future is so uncertain, and it's that way for everyone, people who don't think about the future are breeding at a much faster rate than people who do, and it's terrifying.
For the life of me, I can't figure out why healthcare (which has long-term effects on peoples' intelligence levels, since a lot of that's not genetic) isn't a no-brainer, but also education. Free higher education is the absolute best eugenic program ever devised-- if your kids are smart, society will invest limitless resources in making them succeed-- because it hurts absolutely no one; it's pure carrot. Instead of getting soaked on tuition, parents whose kids get into top schools should get paid.
