thats a cool assumption.
Our industries are routinely telling people who just spent 4-6 years in training that tough shit, you picked the wrong career.
You are looking at this with a lens of stability that no longer exists, which I personally believe is a major component about why everyone is so unhappy.
You cant just reach a level of life that you are comfortable with and stay there anymore. Its a constant cycle of learning new skills that are then useless then learning more skills that are then useless, ad on infinitum.
