Second, I think my brain is hardwired to ask these questions. To me, it's a systems problem like an engineering problem.
The difference between burritos and politics for me is that the questions I often ask are about people. Who benefits, who is being exploited, are people being treated fairly. I'd use the word justice, but that's a pretty loaded term. When I play a game, for instance, I wonder how people were paid, was there crunch, etc.
I cannot turn this part of my brain off even for things I enjoy. Again, it's like handing me an interesting engineering problem -- I'm going to be thinking about it when I'm not distracted.
