When the lockdowns happened due to COVID, it was just incredible at the sheer number of jobs that could have been done at home.

Some people, like Sam Seder from The Majority Report, speculated that people will use this in the future to leverage their power as employees for added privacy and flexibility in working.

The other thing is that businesses could save on massive costs by simply not, as others have mentioned here, leasing/building/renting/whatever large office spaces, and those former office spaces can be made into something else, like more afforable housing.

But everyone just kinda forgot, or seriously underestimated, at the desire for businesses to have control over their employees. This is one major reason why so many businesses want private healthcare. It allows them to fuck over their employees more than they would otherwise, even if it is much more expensive for them to do so than just paying a tax for public healthcare.
