I do hear you. Sort of answered in another question, but I think “private sector” is very broad. If I worked for a hedge fund, or a big 4 bank, or an investment firm, I might find it hard to know I was literally just making the rich (men) richer.
but the private sector does also cover the arts, believe it or not. So think TV and music and film. That’s broadly where I am, without being too outing.
when I think of my parents and my in laws, who all work so hard for the public sector and have their whole lives, when I imagine them on their hardest days when they have given their all and just don’t have any more left in them. I remind myself of what it is that they do. They go home and put their feet up, and they might watch a film, or a good series, or go to the cinema, or read a book. All of those jobs - production, film, publishing, music - are private sector. They give people joy. I find a huge amount of purpose in that, every single day.
