As has been pointed out by many people, while Columbia is to a large extend a social club for extremely privileged young people, the extensions being built are largely intended to support research work, the output of which is a public good. Apparently, Columbia's research facilities are genuinely and alarmingly overcrowded.

It is misleading to suggest that Columbia is arranging to have private property seized simply for the benefit of those wealthy enough to attend Columbia.

I'm opposed to the underlying doctrine of eminent domain that suggests that land can be seized if the parties who it will be granted to can make better overall economic use of it, and thus I suppose "opposed" to this instance of eminent domain, but it's still important to have the facts straight.
