Companies usually have their factories built in less developed nations since it is cheaper to pay for workers and supplies
Economic euphoria in the United States began in the early 1920s, where large companies began to invest in bonds on the stock market. The economy showed an infinite sea of possibilities. Exaggerated consumption, high profits and the whole culture of the American Way of Life. A whole culture built on the pillars of market and consumption.
However, from this growth was projected that crisis that is considered as the largest that Capitalism has ever faced. A systemic crisis, where the hitherto winning capitalist model decays. The economy that largely revolved around stock market speculation, and therefore artificial, thus found its limit and breaks at the time of the "New York Stock Exchange" on October 24, 1929.
The main factors leading to the crash were the result of the economic euphoria itself. The increase in consumption caused industries to increase their production as well, however at some point there was no longer a market for such a large production which caused countless industries to fail because they could not sell their productions.
Another factor of the great crisis was agricultural overproduction. The agricultural market as well as the industries, accompanying the growth of consumption began to produce more than the market could absorb. Mainly wheat production was affected by the downturn in the market.
