“Transferring childcare from a mainly unpaid feminised and invisible form of labour to the formal paid workplace is a virtuous circle: an increase of 300,000 more women with children under five working full-time would raise an estimated additional £1.5 billion in tax.84 The WBG estimates that the increased tax revenue (together with the reduced spending on social security benefits) would recoup between 95% and 89% of the annual childcare investment.85 This is likely to be a conservative estimate, because it’s based on current wages – and like properly paid paternity leave, publicly funded childcare has also been shown to lower the gender pay gap. In Denmark where all children are entitled to a full-time childcare place from the age of twenty-six weeks to six years, the gender wage gap in 2012 was around 7%, and had been falling for years. In the US, where childcare is not publicly provided until age five in most places, the pay gap in 2012 was almost double this and has stalled.”
