That certainly would be nice, but the risk to the individual that they are just exploited on a meagre salary for 3-6 years to only benefit their advisor has become so large that I don't recommend doing a PhD to anyone (or at least think very hard and very diligently investigate the prospective advisor and the faculty). Even if this means we as a society are losing out on scientific discoveries.
