As a manager: some people can work from home, and some just can’t. The problem is, you don’t know which is which when recruiting, and firing someone even remotely in a protected class is a huge hassle.

Even so, if I were to start a company today, I would try very hard to hire remote, for many reasons, the most important of which is this would dramatically expand the talent pool, and (I believe) lead to less stressed employees and better results. People who lack intrinsic motivation typically don’t perform well even in the office.
