Quitting implies there is a problem, the authors even state so. But is it really¹? I'm quite sure "Over 90% of college students quit college within a decade". They graduate. Should science grow exponentially? Is there no value in a PhD graduate that isn't a researcher? Get everyone a PhD and chain them to a desk for research!
