Yes they can tell people to move in the name of public development. But it’s not like they just kick people out without compensation. My wife’s grandparents’ and parents’ had to move. The government provided them with new housing. The new houses are more modern, with toilets and running water, which they didn’t have before. The new houses are located in better places. Oh, and they have houseS now — previously they only had 1. Their standard of living improved.

That is a completely different scenario than what would be the case in many areas of the US.

In 2012, Amtrak estimated $151 billion to upgrade the Northeast Corridor (Washington DC to Boston). Adjusted for inflation that is about $168 billion now. I would assume that the actual price if we proceeded would be much more as I've never heard of a large project like that in the US coming in at the budgeted number.

It is a huge amount of money that can't realistically be recovered by train fares so you have to ask yourself is that the best way to allocate tax dollars? There are lots of other things I would choose to spend $168 billion on and one of them would be not collecting those tax dollars in the first place...

>Infrastructure is easy (and cheap) when you don't have to respect property rights or do environmental impact studies.

Is there no national/public interest exception in the constitution just for such cases? Where you take someone land buy you pay or give equivalent land back(I know some people would like to get rich quick in this situations)

In the US? There is, but it's not always politically popular, and fair market value is required, which gets expensive when tearing down buildings and moving highways in Urban areas.

The bigger obstacle is the environmental impact study, which includes a social justice component. That keeps you from using the cheapest routes, as cheap land usually means it disproportionately affects minorities.

China's situation is similar to the US in the 1800's when land was basically free and railways were being built everywhere. There is little US land availability today to build infrastructure on, same issue in a lot of europe

See my comment above re: estimates to upgrade the Northeast corridor lines, presumably some of that is $$ to acquire land via eminent domain.

Yes, there is: https://en.wikipedia.org/wiki/Eminent_domain_in_the_United_S...

environmental impact studies were not done for highways either and they are much worse environmentally.
