As much as I would like to say "Yes" I know that it is neither humane (to an extent) nor would it work. It would be taking away one of the most instinctual, perhaps the most instinctual, thing that a human (animal) can do. To put a law on having kids just makes me feel like the Government is becoming more and more like some sort of freaky, controlling 1984-esque monster. Having to have a "Children Lisence" would be incredibly over-the-top and a terrible thing for the Government to do.
Furthermore it would not work, how would this be regulated? What about countries that don't have the law? Surely they would soon massively outpopulate the countries in which the law is in effect. If would be almost impossible to introduce it to 3rd World Countires which already have a massive population and are filled with poverty, it would wreck havok and the Government would have no way of controlling it effectively.
I think that the Government should spend more time on things that matter, and yes I know that this is a very important issue, but putting it into effect would waste years and years of the Governments time, and the law obviously wouldn't be put in effect for years to come.
It honestly just does not seem right, there have always been stupid/ignorant people in History, I don't think that putting in this law will change anything dramatically, as well as the fact that it impedes on the most free and natural animal instinct to have - to reproduce.
Also I don't know how effective it would be, take for instance the woman who accidentally let here baby drown while she was on Facebook playing Cafe World. She probably would've easily passed that test, she thought she would be a great mother, she looked after he child, however she made a mistake and because of that her baby drowned. That test would not have a made a difference for her.
Even an incompetent Mother or Father who takes this test, and fails, can retake it again and again until they get it right. It isn't going to change their attitude to raising a child that much.
Yes I agree that it is terrible when you see stupid people, and it's terrible when you realise that they're probably going to have children. But denying them the right to have children (until they pass a Government made test) just isn't the right thing to do, it's denying the most basic right. I hope to God that this law never happens.
