Honestly, I don't think any metric can fix it, and don't have any easy solutions to this. The problem is larger than academia, more endemic to society. The root cause is society's values have changed. Previously, prestige mattered for something. Now, people would rather listen to pop stars than learned individuals, and wealth is the only metric that matters. As a result, typical professions that used to confer prestige, and for which prestige was supposed to be just reward, such as a professor, a medical doctor, a judge, are now mainly pursued for pecuniary reasons (money, job security). And because they're not doing it for prestige, they don't necessarily care about being right/correct. Playing the game to maximize the revenue streams is paramount. I happen to know a number of faculty who are quite proud of their multiple revenue streams. This would be unthinkable for an academic 50 years ago.
