There are very, very different views about the role of government and religion in this country, very different takes on morality, responsibility, and lots more. These are not resolvable via compromise. If things are relatively good economically, people can generally agree to disagree. When things are not so good financially (e.g. after 30+ years of the destruction of the American manufacturing sector and wholesale movement of capital and labor offshore), this becomes much, much less easy.
The answer to "Can't we all just get along" is, fundamentally, "No, unless we're all doing so well that we don't have to care".
I spent a lot of my time telling my three kids they have to learn to compromise [with each other!], since the alternatives are much, much worse.
Q: What's the plan for reconcilling "very, very different views" if one is not going to compromise?
1. civil war 2. political power (domination) 3. secession 4. overwhelming economic prosperity
Umm, there would appear to be a fair bit of collateral damage in those first three. Are you sure you're going to end up on the winning side?
Compromise is healthy. Maybe you should reconsider.
