It depends on your perspective, no?

If the perspective is that everything is disconnected and that you are more important than everyone else then yes, it does.

If one can see that all is connected and everything affects everything else then it makes very little sense. Those taxes pay for poor people's sustenance when they cannot work. They pay for people who can't afford private healthcare. It's rational to help them because more national unrest means more stress, less productivity and, in the end, less likelyhood of people buying your products.

The problem with being perfectly rational is that one may not consider the flaws in one's assumptions. Rationality is only as good as the information it's acting on and is not a silver bullet for making the right decisions. A blind man might conclude that while the sun may be hot at times, it's also extremely dark.
