Self-actualization when working a job for mere survival doesn't happen because of the job, it would happen in
spite of it.
Succeeding in spite of something means that something is an obstacle.
Usually, it's good sense to remove obstacles.
There's little any single person can change in this world, in reality. It's a large and complicated place and most change requires machinations much larger than an individual.
The nature of the work we do while we're alive on this planet is one of the things that humans have the real ability to change.
Modern society does require that we operate interdependently and cross-disciplinarily. We need people working in various strata and with various skillsets, but that doesn't mean one shouldn't pursue their passions.
Why would you reject what you love rather than pursue it? Money? That only makes sense when it's a matter of raw survival, and if it's a matter of raw survival then you're not on the path to self-actualization, you're on the path to cortisol-fueled live-or-die decision making.
Money's not a measure of a person. It's nothing more than a stand-in for energy transfer.
Real value and the road to self-actualization is in your experience in life, and if that is overwhelmingly negative in your day-to-day and you are continually separated from what you love then guess what kind of life you have had?
