Amos, you can't have it both ways. It's either "too late", or it's not. If it's not too late, then we can "turn things around", as you say.
I firmly believe that it's not too late, and that we have it within our power to turn this country around.
I concur with the balance of your post.
Old friend of mine sometimes quotes his Granddad:
“Can’t never did anything.”
