You've missed an important point in the previous post and then in the last post, you point out the obvious, that, on a general level, those who are having the most children are also the stupidest, while the most intelligent are also having the least children. This has been going on since the Neolithic era, which is why human average brain-size/average intelligence has been steadily declining since. One only has to look at all the great scientists/philosophers - almost all of them ended up childless.
As regards welfare, plenty of very intelligent people have exploited the system very well. After all, it is rather stupid to pay taxes which then go to support and enable others to have children on welfare. The links I provided proved the point. Sure, a few like the above get caught, but most do not because they are careful enough to stay within the law. Take 3 successful examples I know of:-
1 Afghan couple with 9 children emigrated to Vienna as so-called "refugees". They managed to collect 8,200 euros a month in benefits, some of which went for IVF so that they could have 2 more children. An Austrian couple anonymously talked to newspapers online and stated that, as long as they only worked part-time, they got all the benefits they wanted, plus if they had worked full-time, they would have had to pay so much extra tax, they would have ended up with less money in the end.
I also have heard of 1 British guy who started out with a council flat provided by the State. He then used the fact that the London boroughs never communicate with each other, being jealous of each other, toapply under aliases to 28 different boroughs, so that he managed to get 28 council flats in all, all in his name. Needless to say, what with enormous, rising house prices and rents in London, he was able to sub-let these 28 council flats for huge rents for several decades, and still hasn't been convicted, afaik.
But this is all irrelevant, and nothing to do with the current thread, which is about ALL mankind becoming less intelligent, this time involving the environmental influence, as opposed to the genetic drop in IQs.
