Not to mention the workers building the track get paid about $200 per month. Construction workers here make more than that in a day. Factory workers making the steel etc, make more than that in a day.
Cost of labor in all aspects from actually building the lines to making the components drastically reduces the cost.
Land value in the US, that are all privately owned, that have to be paid. In China if anything is privately owned they just take it.
And as I said the US culture has become much more dependent and used to driving, we just dont care that much or want that much to get on a train, that takes longer than flying, and costs more than driving.
And like I said, people would rather fly for same or less money, than a train, especially when a flight is much shorter time. There are only 13,800 domestic flights per day in China, in the US there are over 102,000 domestic flights per day. Rail is more of a necessity in China. About 75% of the US Population has a drivers license, only about 25% of China's Population has a drivers license. In the US there is about 0.8 cars for every person. In China there is only about 0.2 cars per person. etc.
The US has much much more regulation, much more restriction, much higher costs etc. trying to compare China with the US is ridiculous on so many levels, there is really not much that is remotely close to the same between each country.
And on and on.
And like above, people just dont want it.
