I think every new-build house or apartment in say London, Cambridge or Oxford will routinely have a little room next to the kitchen, big enough for a single bed, with an adjoining cubicle shower and toilet, for the maid - following the Latin American model.
She will be childless and will be paid Osborne's new Servant Wage - the amount needed to live in a city if you have no accommodation and no children.
British parents will struggle with the idea of their children becoming childless servants again, but they will be able to console themselves as she may even have a qualification, say in childcare.
There will be no need for domestic workers visas, as all the live in domestics will be home grown, like in the good old days.
Routine live in servants will be not just desirable but essential, if you live in a house, as you won't dare leave your home unoccupied - and probably wouldn't be insured to do this.
Property prices in London and the South East will continue to rise, not because we are productive, but because of even more capital flight caused by unrest elsewhere in the world and our internationally recognised benign tax regime.
After at least 20 years of conservative government - (small c or big C - won't really matter), it will cease to matter who is in power, because we will have signed away all our democratic rights through trans-national trade agreements which allow corporations to sue governments who change the laws in ways that cost them.
