If we have the money for it? Sure we do, we're taxayers. We pay a very large portion of the capital costs of the Amtrak operation, and on the long-distance trains the "farebox" or ticket revenue covers about 50-55% of the operating expenses of each trip.
Just because you are a taxpayer who subsidizes Amtrak does not mean you can afford to ride Amtrak. It’s more expensive than flying. And flying is more expensive than driving.
We use the roomettes on Amtrak. I wouldn’t want to go coach on overnight trips. These are quite expensive!
