Growing numbers of university graduates from developing countries are heading for well paying jobs in the U.S., Britain, and Europe. As technology has grown so has the demand for skilled employees. The IT industry, especially in Silicon Valley, is dependent on Indian and Chinese software engineers. In Britain, the shortage of public sector professionals has led to an explosion in the recruitment of doctors, nurses and teachers. This demand for skills has lead to competition between countries, many introducing new programs, like Germany's "green card" scheme, free immigration assistance, and the U.S. H1B temporary visas. Some experts believe that developing countries benefit from the loss of these highly skilled workers as many send money home and when they eventually return, they bring new skills and assets that increase living standards in their native country.
