This problem, like many in modern day science, can in large part be traced back to unstable funding. On the Maslow's-style hierarchy of research lab needs, the need for funding is a lot lower on the scale than the aspiration for scientific purity, just as a human's need for food is lower on the scale than their desire for self-actualization. If competition for research dollars ceases to be so cutthroat, it will go a long way towards solving this and many other seemingly entrenched cultural problems.
