Isn't FIRE, Finance, Insurance, Real Estate? These seem to be the folks who are most deeply invested in returning people to work. The people who took out massive loans on these properties to develop them, with the expectation of steady rental incomes. A secondary effect of the abundance of unrented office space is a slump in development, as well as a slump in the value of residential properties in the immediate vicinity of these downtown economic zones (Who's going to pay premium rents for an apartment in Midtown when they can telecommute from Maine?). Insurance, while being a very broad industry, is tied very closely with the Real Estate industry, and because of the extreme commodification of housing, this has broad effects on the entire financial economy.
