I agree, with the caveat that history always has a knuckleball in store for humans. I think improvement will come, but I do not have a clue in what form. Remember Abraham Lincoln lost the last political race he was in prior to the presidency, and was so depressed he could have said “You won’t have Abe Lincoln to kick around any more.” Remember that US public opinion polls were 70% against entering WW II . . . on December 6, 1941. Things can change in a heartbeat. This illegal immigration stuff is enormous, and may force the RINOs back on their heels for a very long time.
You’re a good thinker with a clear vision of the long game. I agree with you. The danger of democracy is a fickle public. Things are always going to be difficult and change moves at a glacial pace, until it suddenly doesn’t. Take care.
