I agree with much of what you two have said. I have said all along that it will all take almost as long to undo as it did to do. But I disagree with this bit:

Right now, it just seems like all the forces are organized favoring destruction. I don't see a way out. If the course somehow is corrected, that's going to take at least a few decades, and by then I'll be too old for it to matter to me.

No I won't be "too old" because by the time I am "too old" I will be able to look back and say what I did to help correct the course. I am hoping that every right-thinking person on the planet will have on their deathbed a satisfactory answer to the question, "What did you do?"
