Sort of. Kinda. Maybe. In my experience, graduate students aren't really that effective at research until several years in to their education. From a productivity standpoint, it is largely a loss. Many would prefer to hire post-docs instead. They end up being not much more expensive after everything else is taken into account, and they are ready to do good work from the get-go (which, for people who's livelihoods depend on getting tenure and/or grant money, is pretty dang important).
