For better or worse, we live in a capitalist economy and people who invest in and develop brands deserve protection under the law, so it’s necessary, and understandably very lucrative, and professionally you are up against very clever people, which any self respecting legal professional should relish - it’s just not really uplifting.
My girlfriend used to work in advertising and she described that industry along similar lines. Very well rewarded, exciting but a bit soulless.
Some people aren’t arsed about any of that though. We’re all different. We all have different priorities.
