It's not just money that prevents people from repeating experiments, it's recognition. The general idea for research to be accepted is that it makes some novel, albeit small, impact on the field, acceptable for publication in a peer reviewed journal or proceeding. Repeating someone else's experiments wont get you that, so in general it wont help you graduate or move you toward a higher position at a university or in your profession, meaning there is very little motivation for researchers to pursue such endeavors. So instead of just throwing money at the problem, we may need to entirely revamp how we recognize the pursuits of researchers.
