Here in Shanghai property rights are becoming more important. The government can't just come in and take your property for their use without compensation.

This is really veering into a conversation better suited for
the NYC transit thread, but the short answer is that the NYC Subway has a more stations per mile than the Shanghai Metro and Manhattan is the densest part of the network station wise. Outside of the center city Shanghai Metro stations seem to average 1.25-1.5 miles apart, the 2nd Avenue subway is building a station about every half mile. At that range the construction impact from the station boxes tends to overlap, not to mention that Manhattan is so built up there's zero space to store equipment other than out in the street. It's a very different project than the extensions of Lines 5, 10, and 13, which are pushing outward from the city center rather than tunneling straight through it.
Property rights in China started improving in the late 00's from what I hear, but they're still fractional compared to those in the US. In the US the government has to take into account the physical value of the land (including what
could be built on it, and how much value it provides to your other properties) in addition to the value of whatever you've already built on it. In China, only the second part really counts.
