I will also give you a good example of two people I know: One has a masters in the “therapy” area. He currently runs a therapy business and makes high six figures.
The other person was a housewife for the past X years. She did not want to be a secretary, to work for $10/hr, so she decided to take a shaitel macher course. She was unable to “make it” due to saturation in the field (too many women trying to be shaitelmachers), and ended up as a part time secretary.
So obviously, shaitelmachering is a bad business, and all therapies make high six figures 🙂
