Encourage WFH and then the company doesn't need to pay for an office building at all! It's almost like businesses have to pay for infrastructure for the employees to be able to do their jobs, whether it's in an office park downtown or the home office in the suburbs.
That'd be totally logical if there wasn't a large amount of investment money tied up in commercial real estate - we've seen a deluge of articles about how detrimental WFH is and many of these are coming from investment firms tied to commercial real estate. We're currently losing the battle of advocating for WFH even though logic is on our side - we don't need to give investors more ammunition for the propaganda mill.
