I think it's a case of "if I don't do it, someone else will". And I don't mean that in the (fallacious) sense of "it's ok that I do bad things, because if I don't, someone else will". I think it's reasonable to look at future progress, recognize that certain things are going to happen regardless of whether or not you're involved, and then make the decision to get involved (if you have the resources to do so) in order to shape how it happens.
