Saying that "we" are all in "this" together is the kind of anodyne slogan deserves to be retired when an election is over, and especially an election that very much called into question both the "we" and the "this."

The USA is not a nation of people with a common ancestry. The USA is a Constitution, a military force, a Federal Reserve Bank and a flag. If the American President does not respect the American Constitution, then the USA has effectively ceased to exist. In the Age of Trump, there may no longer be any "this." 

Sixty years ago there may have been a supermajority that called itself "we," but the "we" is rapidly dying off with the generation that won WW2. Now "we" include people who hold passports from and swear allegiance to hostile nations, people who regard the USA as their "oppressor," and people who despise George Washington and refuse to read Melville. It is not surprising that people refuse to buy health insurance for others who despise and hate them.
