I heard one of the witnesses in the previous group say that the problem isn't that there is a shortage of doctoral or postdoctoral students; there is actually an oversupply, and they can't find jobs in their specialities. A lot of them get discouraged and leave the system, if I can put it that way, and do something else. They stop using all the knowledge they have acquired and stop putting it to work for the private sector, in various sectors of the economy, or for the environment, for example.
So yes, there is a loss of this knowledge. We need incentives for these people, for them to see we support them.
