As long as they have degrees given them by other social experts who caused other disasters, we pay them, we respect them, and we listen to them. When no one demands that a policy WORK, the right degree has always been a license to kill and wreck while getting paid for it, whether in the social sciences today or in yesterday's medicine. The argument is that the more lawyers we pay for, the more justice we get. There is not the slightest trace of evidence for this. But we don't ask for any.
Lawyers have degrees and judges have credentials.
Since we worship those degrees and credentials, and are happy to pay for them, we assume that they are of some use. Thinking that credentials are necessarily related to justice is exactly like the medical bleeding that went on for almost two thousand years. It is more than useless, it is destructive, but we pay for the degrees and experience and credentials without asking for any proof that they provide justice. Again, we have never asked for any such evidence. And, as I keep pointing out, in the real world, the public gets absolutely no more than the public demands.
