From my point of view as a foreigner the US political system is broken and nobody tried to correct it so this was only matter of time. And yes when something like this happens most people just want to get by.
After my bikepacking trip I will pitch the interrail to my parents. They are so excited about the places I visited but don't know how or if they will be able to get there. They (me too) don't like flying and by car it is just too stressful.
