That's funny... Americans don't have an economically rational aversion to becoming movie stars in much the same way.
The serious question is whether we should launch a PR campaign to encourage young people to make decisions that may lead (at least according to RAND) to long training times with poor pay and career prospects relative to other paths typically available to the "best and brightest".
It's very possible that the best and brightest could live in greater comfort as criminals than scientists, but even if that were the case, any rational government would encourage them to be scientists since that would be better for the country.
Edit: Seriously? Care to explain your reasoning, downmodders? Why would a government encourage decisions that are destructive to society?
Still, I recommend you read the rand study. They discuss ways to make sci/eng more appealing rather than launching a pr campaign to merely make it appear more appealing. The second could end up creating an even greater aversion to this career path.
