I feel many of your ten points are true short term, but I'm prone to be long-term negative because of human short-sightedness and complacency.
Unfortunately for us, Republican's cyclic "two Santa Clauses" tactic is still working for them in the long term. It does, however feel good that we're about to go into the "positive" side of that cycle.
Until the massive problem of global inequality is resolved, I fear the trends toward nationalism, protectionism, racism and worsening poverty and deadly conflict will continue.
I don't see much now to stop the process unless we experience a global cataclysmic event such as another Great Depression. Climate change will eventually do the job, although millions will die in the process. The world is very poorly prepared for it and still in denial, much like Indonesia has been for tsunami.
However, let's hope 2019 proves to make all of your points hold true for the sake of world-wide emotional relief.....
