Ever since the British parliament passed the Town & Country Planning Act in 1947, housing in that nation has gotten less and less affordable. As a result, the average size of new homes today is only 925 square feet, down 44 percent from the average size in 1920. Meanwhile, the average size of new home in the United States in 2013 was 2,598 square feet, up 56 percent from 1,660 square feet forty years before.As the post points out, this isn't a party issue - both major parties are essentially identical on this, just as both major US parties are identical on the issue of immigration.
Eric Pickles, Britain’s community secretary, blames the problem on “Labour policy, which decreed that at least 30 homes had to be built on every hectare of land” (about 12 per acre). But we know the problems go back well before the previous government, and the Tories had plenty of chances to reverse the policies in the Town & Country Planning Act.
Instead, this is an issue of class war waged by a self-anointed "elite" against a middle class they hold in contempt.
