When republicans say "Make America great again," they are implying that America is not, presently, great. Like those low points during, say World War II when we imprisoned our fellow citizens in concentration camps because they were of Japanese descent, or when we were persecuting fellow citizens for their political beliefs in the 1940's and 50's. What is their evidence for America's current lack of greatness?

I think America is pretty great; we get a lot of things right. I could offer some tweaks, but my issues are (in no particular order, and in no way comprehensive): wealth and asset inequality, poverty, racial justice, education equality, continued LGBT equality, campaign reform and voters' rights, environmental protection and reclamation, thoughtful and rational foreign policy, gun safety and control, utilizing evidence-based policies for effective government intervention, and a pony for everyone.

I'm guessing these are not the same issues been discussed at a GOP rally.
