No, I don't believe so. Some might, but I think many do it purely for the selfish reason of avoiding guilt etc. Just because you and I and many others see it as being good for everyone, I don't beleive that most people think the same! They may be able to describe the act of doing something for the benefit of all, just as we are discussing, and understand it, but otherwise only want whatever they want regardless of the impact on others. Humans are selfish, all of us are, it's an evolutionary tool for survival used by all life and helps ensure the survival of the species. Some of us regularly think beyond that though, but I reckon you'd be surprised how few do with any regulatory, it can become quite tiring to constantly assess situations afresh, so instinct kicks in and so people just do what they want in that moment that takes the least effort.
