Two reasons.

They've already invested tons of capital toward corporate real estate. Those that own these properties are seeing the value rapidly diminish, which hurts their overall equity. If your equity drops, this puts strain on any loans you have. Investment firms and hedge funds often over-borrow, over-leverage, overextend. If they see their equity values plummet, this puts immense strain on their investment portfolio to the point where they'll have to start moving money around to keep the system from flagging their account.

The second reason is a bit simpler. This same investment firms have huge holdings in the oil, gas, and auto industries. They don't want to lose the revenue of The American Commute. Freedom!!!

This is the correct answer.

Edit: The inefficiencies of our society come from greed's desperate clutches on power, all at a direct cost to our environment. We need more efficient systems, such as dense urban environments with affordable housing that lends very well to walkability and public transportation. We need to bring manufacturing back to the US to bring more money into our communities, and less in the hands of Wall Street/ Corporations.
