They just raise taxes when they want more.

Johns-Hopkins replaces about 75 computers per year. They used to donate them
to various worthy causes, but that process turned into a nightmare. The
receipients couldn't make them work, they had no software, the accounting
department complained about the tax tracking problems, yak-yak-yak.

How did Johns-Hopkins solve all these problems at a stroke?

They leave the computers on the sidewalk at night for the Urban Fairies.

Dilbert's boss recommends leaving obsolete computers, again at night, on
school playgrounds. That's what he did with his refrigerator.
