History indicates that the pendulum goes back and forth. Some great civilizations have grown old and corrupt and gone down the tubes, but I don't think America is ready yet for that, despite the best efforts of those in the media, academia, and the entertainment industry to make it so.
In the Catholic Church the dissenters are getting older and older, and few are taking their places. Tragically a lot of younger Catholics have dropped out because they were miseducated in the faith by these dissenters; but the Church as a whole is starting to turn around.
Some institutions are so far gone they may never recover. The Ivy League Colleges, for instance, may simply be replaced by other institutions who do a better job of educating their students. Religious orders will collapse and others will take their places. The Democrats may implode, leaving some third party the change to become the new second party.
Let's hope. America still has a lot of flexibility, a lot of energy, and a lot of promise.
I see this on my advice website. The younger ones look for conservative advice. The screaming forties and fifties hate me.
