You cite the dismal perception from 2006-2008, but what changed? In 2008 Obama was elected and everything is new again and he won the Nobel. Did the country completely change in 2 years? Has it changed that much in 8?
Not really, that's why getting so riled up over singular negative events isn't worth your time. Things change fast, and countries have long histories. Germany and Japan were ruled by jingoist elites for centuries and just 80 years ago they were culling populations. Today they are examples of doing it right. Do we really believe 4 years of a bad leader is gonna flip centuries of progress?
It's an issue, yeah, but let's not overstate it because that' s not being honest with ourselves.
