I make an effort, in my role as an older member of my department, to reinforce knowing history. Not only of the industry, which critical to avoiding errors already made, but also general history because it helps create a more advanced social order. The critical part of any social order is trust. Without it, markets fail, relationships fray, and good behavior is set aside in favor of self-interest. History, at its core, teaches the value of trust.
All good teams, departments, interactions, communities, and even nations are built upon a basic level of trust. It is rarely discussed, but absolutely essential.
In the U.S., trust has begun a slow dissipation. Think of an example of someone who did things the 'right way' and was moderately, or supremely, successful (let's say the Boston Red Sox of 2018) versus those who do things the 'wrong way' and are supremely successful yet go unpunished or are barely touched (the Houston Astros of 2017). When we fail to punish those who gain rewards improperly, we reduce the ability to trust our institutions. How often have you talked about someone you admire, only to have someone else say "if he/she is so smart or good, why did person X (who wasn't as 'clean') make all the money?" That kind of response typifies the slow fraying of fundamental trust.
Another example could be our recent trials and investigations regarding Trump. In this, we see an example of retributive anger (Trump won and I hate him so he has to go), which is very damaging and occurs with the complete loss of trust (can anyone argue that the Democrats trust Trump even a little?). Transitional anger, the anger we feel as we shift from one order to the next, that sense of loss yielding anger but without feeling the need to lash out, is manageable and useful. It can help people progress. Retributive anger is dangerous and undermines the fabric of trust that is necessary to move forward.
The Democrats are suffering now because of the fact they have engaged retributive anger. They're mad they lost an election they assumed was theirs, and rather than be angry at their own shortcomings and using that anger in a transitional manner to improve themselves, they've lashed out and are destroying themselves and potentially the nation (if their behavior is followed to its logical conclusion).
We are successful as a nation because we have an innate trust in our political institutions. That trust exists regardless of those in power because the Constitution protects us, as individuals. Even if bad people are elected, one person and even a few cannot destroy the system. Checks and balances assure that. We can survive a bad president (and have many times). There are reasonable methods to oust the truly awful. Engaging those levers in wrong-headed attempts simply because someone is 'offensive' undermines that innate trust of our institutions. It causes some, and possibly many, to question the validity of our original belief in our Constitution and our laws.
This doesn't happen because of one person. It doesn't happen because "Trump did it," it happens because a group of people are hoping and trying to undermine that trust, and it isn't the Russians. Or the Chinese. It has to happen internally.
I don't love Trump, I barely tolerate him. But I've not liked plenty of presidents. I've had trust in our system, though. Thankfully, after two clear attempts to undermine that system, it has stood up to the attacks on it, and I still trust it. It's a shame there's an entire party out there so far off base that its members no longer trust the system and are proposing potential candidates to destroy it.
