Why is Amtrak so absurdly expensive?

I would just like to comment on how you disregard fuel costs because Amtrak is electric. It is also a pet peeve of mine about people talking about electric cars as "green". The vast majority of electricity comes from coal, natural gas or uranium being used to create steam to turn a turbine generator. Hydroelectric power is the only economical alternative. Solar power and wind turbines combined generate less than 1% of all other electricity.
