It has been theorized that though such continuous stimulus may lead to greater growth on paper, that growth is more likely to be malignant than it would be were the economy allowed to grow at a more natural rate. Furthermore, continuous inflation is also at least partially responsible for the business cycle. The price of money is the interest rate at which it can be borrowed, and constant inflation is what keeps interest rates low. When money's cheap, people tend to borrow more of it and are less careful about what they do with that money. Hence, due diligence declines, and economic bubbles become more likely.
