What is the reasoning behind this little gem- or isnt there any!

The Conservative government are about to hand yet another tax-break to the rich as plans to give wealthy parents £2,000 each in order to send their children to elite private schools are due to come into effect next month.

This ridiculous financial aid for rich parents comes as part of the Tories’ ‘tax-free childcare scheme‘ – due to be in place across the country by March 2018 – which will give a 20% Government top up on money spent on childcare, with a limit of up to £2,000.

The scheme will allow parents to claim support for kids sent to fee-paying private schools, despite the fact that the Tories had promised to phase out taxpayer support for private school fees under the old system of childcare support.

I am struggling to find a reference to "£2000 is payable to both parents" apart from the independent but not unbiased article in the link. It says both parents need to be working and £2000 per child.

Thank you DD and Salmon
sadly I am earning too much to benefit, and my children are a tad over the age threshold.
