The report has been criticized by academics, economists and businesspeople. Critics claimed that history proved the projections to be incorrect, such as the predicted resource depletion and associated economic collapse by the end of the 20th century. "The Limits to Growth" faced ridicule as early as the 1970s. The methodology, the computer, the conclusions, the rhetoric and the people behind the project were criticised. Yale economist Henry C. Wallich agreed that growth could not continue indefinitely, but that a natural end to growth was preferable to intervention. Wallich stated that technology could solve all the problems the report was concerned about, but only if growth continued apace. By stopping growth too soon, Wallich warned, the world would be "consigning billions to permanent poverty".
