I mean, brilliant ideas can still be fun to work on. Who cares if you don’t get appropriately rewarded for saving the company $50k/month, it was time well spent.
As opposed to working on that pointless crud thing your boss likes.
I agree with you. But not everyone will. Some people have jobs to pay for their lives outside of work, and that's it. And that's fine.
I take the stance of, the job I do for 8 hours 5 days a week might as well be something I actually enjoy doing above and beyond the financial incentive. Working on something I think is really neat is enjoyable, and I'm lucky to work in an industry doing things not so far from what I would spend my time doing anyway if I were retired.
