"Right to Buy thus created an astonishing leak of state money – taxpayers’ money, if you like to think of it that way – into the hands of a rentier class. First, the government sold people homes it owned at a huge discount. Then it allowed the original buyers to keep the profit when they sold those homes to a private landlord at market price. Then the government artificially raised market rents by choking off supply – by making it impossible for councils to replace the sold-off houses. Then it paid those artificially high rents to the same private landlords in the form of housing benefit – many times higher than the housing benefit it would have paid had the houses remained in council hands. In other words, since Thatcher, the British government has done the exact opposite of what it has encouraged households to do: to buy their own homes, rather than renting. Thatcher and her successors have done all they can to sell off the nation’s bricks and mortar, only to be forced to rent it back, at inflated prices, from the people they sold it to."
James Meek explains the farcical consequences of the Right to Buy scheme, in the course of a lengthy but engaging piece on the national housing crisis.
