Is the right hon. Gentleman aware that, with a slightly smaller population, West Germany builds 570,000 homes year after year, which is no miracle because that country devotes 5·8 per cent. of its national product to this purpose? Cannot the British Government devote an equal proportion to this purpose in our country, as many of us believe that unless 500,000 houses a year are built for the next ten years the tragic housing situation in our country will remain?
