“This is a nightmare, which will pass away with the morning. For the resources of nature and man’s devices are just as fertile and productive as they ever were. The rate of our progress toward solving the material problems of life is not less rapid. We are as capable as before of affording for everyone a high standard of life … We were not previously deceived. But today we have involved ourselves in a colossal muddle, having blundered in the control of a delicate machine, the working of which we do not understand. The result is that our possibilities of wealth may run to waste for a time — perhaps for a long time.”

John Maynard Keynes, 1930
