It’s an article of faith: the United States needs more native-born students in science and other technical fields. But a new paper … contradicts the notion of a shrinking supply of native-born talent in the United States. In fact, the supply has actually remained steady over the past 30 years, the researchers conclude, while the highest-performing students in the pipeline are opting out of science and engineering in greater numbers than in the past, suggesting that the threat to American economic competitiveness comes not from inadequate science training in school and college but from a lack of incentives that would make science and technology careers attractive. Cranking out even more science graduates, according to the researchers, does not give corporations any incentive to boost wages for science/tech jobs, which would be one way to retain the highest-performing students.
Same apply for everywhere I guess.
