Who is this "we?"

There's a kind of circular complaint built into all such endeavors that goes like, "we can do this, but unfortunately we as a group don't want to, but we could definitely do it if we wanted, but sadly we currently have the wrong opinions, but we can definitely do it, if only we weren't inclined not to, but we should and we will, as soon as we all come around to the truth."

Your "we" doesn't seem to want to do what you want them to do, which is why communists so often end up thinking that the real problem is the existing populace and maybe what they really need is to be re-educated or even replaced.
