Are there lack of professionals?

Is there really a shortage of people in science, or not? What are the views? The article say there are few people applying to graduate school? I think it is not because of the lack of supply, but rather, there is not enough incentive for US students to pursuit PH.D in the sciences. US students must have come to the realization that engineerings are taken by Chinese, services are taken by Indians, and software are taken by both. The large pool of engineers in Asia produces access supply, thus, reducing the mean salary in these areas. In the age of globalization, the multinationals could simply hire engineers from China, and India with reduced cost. This is also the case for the service industry( Tax collection, accounting etc). With the integration of the global economy, there is simply no more incentive for us students to go into high risk professions. Why go get a ph.d in engineering when someone in Asia can do what you do for half your wage. Since grad school needs funding, so they have to, by necessity, get foreign students into US programs. Because of the lack of career prospects in engineering, and service, the US students must necessary go into professions like law, banking, or medical professions. Law professions are really not very rewarding because of the long hours. Banking is to hard to break into, and the medical profession would probably suffer with the introduction of Watson.
