The issues are profound.... but I think it's in our DNA to handle adversity and move on.
Also... one of those issues is that there is a high level of general ignorance among Americans. For example.. a legit sizeable amount of the country doesn't know who the VP is.... and even more who the Speaker of the House is.
So... Hillary or Trump wins... there is anger from a sizeable amount of people... the anger stays... but people return to their lives.
Nobody says life will stop... but what is stopping at an alarming rate is families who are middle class... this is not just some passing squabble issue... it's about the economic foundation of our society...
We destroyed Communism over a 50-year period by beating them according to their own criterion: which system did a better job of providing a decent life for regular people. That was their criterion, not ours. But we beat them at it by having a very restrained, moderate, and regulated version of Capitalism. While that was going on, Capitalism was not deified... while it was going on, the basic American position was the Capitalism was the worst economic system except for the available alternative.
Yet, somehow, as soon as we won the Cold War, that somehow got twisted around into unrestrained, immoderate, unregulated Capitalism getting credit... which it didn't deserve because that's not what won the Cold War, it was the restrained version that did it. But now we've had 30+ years of the wrong version of Capitalism getting more and more dominant... and now we see the FX: it's killing the middle class in ways that not only were predictable, they were very explicitly predicted.
Neither party wants to admit that... which is how we get Hillary wanting to tweak the status quo... when tweaking will just provide minor adjustments to how many crumbs are tossed towards regular folks while overall wealth gets more and more concentrated... unless/until this is addressed, things will not get better in any meaningful way...
