That is a huge pressure, but it’s less obvious why a company in a business unrelated to real estate would want real estate prices high.
The secret is that companies aren’t in the business of making a good or providing a service, they actually are just giant schemes for raising money for “investments”. For example, airlines don’t make their money off of selling tickets, but through prospecting jet fuel. Most companies aren’t as direct and clear about what their business actually is.
Also the link between real estate and all of jobs isn’t very clear and is very abstract. It’s easy to see the costs and interactions with companies forced by working in an office, it’s difficult to see how a building losing value effects anyone.
