Hey Brian. I would strongly encourage you to keep an open mind about what medicine can or cannot be. If you look into anthropological literature it is very clear to me that our ancestors have used altered states of consciousness to heal and move trauma for hundreds of thousands of years. The rates of remission for things such as alcoholism, ptsd, and even opiate addiction are far higher with psychedelic medicines than conventional treatments based on some of the studies I have seen. Not to mention these studies are being done at mainstream prestigious universities such as Johns Hopkins, NYU, Stanford, and MIT.
Lastly I will say that based on the tone of your post it seems like most people in our culture, you too have unhealed wounding in yourself. Whether your path is to interact with entheogens or not is your choice. I will say that in my experience nothing is more valuable than your own emotional health and the ability to love yourself and love others as fully as possible. I would be more than happy to connect if you want to talk about different forms of healing.
Also to clarify your original question, my father inherited a family business which he ran successfully for 40 years and due to changing markets had to shut down and he never formally studied real estate.
