I'm not sure I agree with that, but I need to give it a little more thought.

The government has been clear they want you to work harder and earn more, they also want you to have children and raise future tax payers, if you do have children either your career and earnings take a hit or you need to put them in childcare, in that case I think all child care should be tax free, they're only in there so you can work and earn and pay tax. It's typical that your wages should increase with experience but you can't un-have children, perhaps you didn't even know you'd hit that threshold when you had them, or more likey that such a threshold even exists.

If we don't think of it like that, but simply that you're no longer advantaged as you put it, the issue is that it's sudden and affects unevenly, two parents can earn £99,999.99 EACH and still receive it, but a single parent or one person in a couple earns that extra penny they're now £2000/child worse off and still have to put their children in childcare.

Of course there's an option to have or not to have children, but I'd argue that the global consensus in countries with ageing populations, like the UK, is that the government want you to work more, and for longer and have more children, so it should be fair to say that from the government perspective, having children is the expected norm.
