RebDoniel, it seems that you have very little of knowledge of psychological experiments. You claim that psychology is purely subjective. That is very far from the truth. In order for a psychological theory to gain recognition as a valid method of practice, it must pass several experiments, ones which are very specific and rigid. You mention Aaron Beck, the founder of cognitive psychology. The reason that his methods have become so widespread is because study groups wh receive his treatments fare much better in the laboratory against a control group who receive no treatment at all. It is very scientific in nature. This is the reason why freudian theories have been largely discarded. They have shown no validity in an experimental situation.
Psychiatry has a very ugly history, but so does nearly every single other school of medicine. The psychiatry practiced today is nothing like it was 50 years ago. Instead of guesswork, we now have ways of measuring the efficiency of any treatment.
I’m not really sure what social work has to do with welfare, marxism,feminism or racialist ideas. Its goal is to help people. Thats about it.
