Instead of using their vastly increased material and technical resources to build a wonder-city, they built slums; and they thought it right and advisable to build slums because slums, on the test of private enterprise, "paid", whereas the wonder-city would, they thought, have been an act of foolish extravagance, which would, in the imbecile idiom of the financial fashion, have "mortgaged the future"; though how the construction to-day of great and glorious works can impoverish the future, no man can see until his mind is beset by false analogies from an irrelevant accountancy.
