I do not know if you are really confused or just sarcastic, but I will clarify anyway. I think that Amtrak was originally supposed to earn money eventually, but that has still never come, so nobody expects it to earn money anymore.
Oh, good. Now we agree that Amtrak is supposed to earn money, even if it doesn't turn a profit. Surely, then, it should do what it can to minimize its losses, and to so minimize the federal subsidy Amtrak receives, within the political system that requires it to maintain a long-distance service of some sort. After all, Amtrak's subsidy is a political issue, just as its maintenance of a long-distance system is essentially a political issue.
