America is too big for planes, too. If your transportation solution is flying, now everyone has to get around via endless highways or big, complicated regional airports, and you can only have so many of those. There's a reason why rural areas in North America have completely different politics from urban areas, and why so much of it is driven by a sense of isolation and abandonment. Trains promise to help here because they are able to stop in small places that will never, ever have practical airports.
A good rail network provides a reliable, consistent, repeatable, and straightforward three hour connection from Nowheresberg to the nearest city. Slow, but good enough to feel like they exist in the same planet. Unfortunately, that promise is subtle, and it plays out over decades, so the reward system we've created for ourselves is incapable of supporting it. And thus, we have Amtrak and confederate flags
It's a term that goes back to the cold war. There was a strike and the Soviet Union ended it violently by rolling tanks into the city. This put communists all over the world into a bit of a dilemma: on one side of the conflict was the working class making their opinion known (a communist value) and on the other the Soviet Union (the good guys). So whose side should they take?
It was British communists who coined the term "tankie" for those who defended the SUs actions to brand them as "fake communists" who are more interested in identity politics (the good guys did it, therefore it's OK) than the plight of the working class.
