I think the China issue is more than just about the returns. The companies don't really have the funds to build new housing either as they rely on new money to fund the projects. I have been seeing more news about those property builders planning on defaulting on their US debt.
I don't know anything about normal english and br english. It's a weird thing to me that there is a difference.
No they don't, especially since people aren't paying their mortgages, so the banks aren't releasing the funds to build.
Yes. Considering US English was once British English - why change?
