In my area (London) there is already a huge shortfall in places because there has been a baby boom. They are constantly opening new schools or creating bulge classes but this is often at the expense of other children who lose their playing fields and there is just not enough room in London to keep opening new schools and there is already a housing crisis because the country is so overcrowded.
I think perhaps it is time the government thought about limiting child related benefits to 2 children (which is the replacement rate) and those that want to have more can do so but not with taxpayers money. It would go some way to stopping some of the problems that rising birthrates create such as the school places crisis, overcrowding, pollution, increasing struggles for resources such as food and water and in an already overpopulated world I think the government is being negligent in not putting some sort of limit on child related benefits, especially when it seems to be counter-intuitive (if you work you don't get more money each time you have another child).
