I will be Prime Minister and I will:
Set up a national system of nurseries for over 2's, free at the point of use, to correspond with the needs of working parents (like in the war). Men will be required to do all drop offs and pick ups.
Introduce free transport to school for all children. Healthy pensioners under 70 will be conscripted to drive everything.
Introduce free school meals for all children, and milk and vitamins, and fruit and veg.
Introduce free prescriptions and dental treatment for anyone who has ever given birth, for the rest of their lives.
Sack every single bloke from the cabinet immediately and build an all-female cabinet with representative women from all age groups. but we can have a token male Minister for Men.
Take all men off boards, apart from a few token ones.
Raise tax to 70% to pay for all this, because actually most women would be better off, paradoxically.
Then I would proffer a small amount of money, say £20.30 a week for the first child and £13.40 for second and subsequent children, to the men, so they had a little bit of money to call their own, for family use. Oh, and then I would take it away if the mother earned over £40k.
That'd learn 'em. Bastards.
