"Yeah, because there was no minumum wage and no high tenement rent & bills for poor immigrants to pay."
Our receding, dice-roll economy is the reason for the unreasonable high value in money. One reason our economy is horrible is because of the lack of stimulation, which is what rail provides. Unfortunately, the government can't run rail properly because it's already investing funds in being inefficient, particularly funding roads and highways. Private companies, under american free market, have real initiative. Take a look at the privately-run Brightline in south-central Florida vs. the publicly funded California CSR. Construction for Brightline began in 2014, while CSR began construction in 2015. However, Brightline got a train up and running in early 2018 between Ft. Lauderdale and West Palm Beach, extending the line to Downtown Miami later on, while CSR were still working on a set of tracks between Merced and Bakersfield, placing the tracks in a corridor that was hardly dense compared to a Los Angeles-San Diego route.
"Don't know what's going with Japan and HK, but given the usual gov't subsidies, doubt that generating money is basic free market."
HK's rail company is so profitable, it subsidizes the government.
"Then again, for example, public transport in NYC, despite getting ever higher, is cheaper than in other countries ayways."
problem with NYC's transit is that it makes 2 miles of tunnel extension into $4 billion. comparing that to Brightline again, brightline's millions for a miami-orlando route was a breath of fresh air.
