Pointless jobs may boost the employment figures, they may serve as a means of ‘social control’. But they also prevent people from realising their potential; potential, which, when freed, could be channelled into pursuits — artistic, scientific, social — that could not only boost individual health and wellbeing, but also benefit society as a whole.
I can very much relate to your description of a pointless job. My last workplace felt like that for me and I could get nearly all my work done in only a couple hours.
After losing that job and starting my own freelance-style career I am much more mentally healthy, and I’m realizing my potential that I was squandering before.
