True enough that on £50,000 and above you should be able to get along without child tax credits - but rather than have poor people have to fill in forms to get it, which would inevitably mean some didn't get it, I think it's better to pay them universally, and have people above the limit pay it back.

Again it ought to be possible to work out a method to ensure that people earning more than £1000 didn't benefit from a tax change supposedly designed to help people below that level.
