Like everything else touched by the federal government, Amtrak is a jobs program first and a railroad second.
But that's why they'll have an uphill battle trying to get it privatized, and why things remain this way. No one is prepared to shut it down without a Plan B in place, and no one will do a Plan B without guarantees. The real problem, if you want to look at it this way, is we force people to commute to an island that's too small and expensive to sustain those people. What we should do is shut down the cities, and disperse the population to other more commutable locations. Then you don't need railroads.
