I share most of your view. There's no physic problem in the US against more train usage. I'm not a politician but it seems there's so many more public incentives in favor of cars and planes that it's a more sensible choice for Americans to use them. Trains are not intrinsically worse in the US, they just aren't helped the same way roads, fuel and airports are.
