ELI5: Why do US Government Agencies have a "Use It Or Lose It" budget model? Why hasn't it been changed to something that stops waste?

The idea of the system is to minimise waste.

If the government provides too much money to a particular agency, they won't spend it all which signals to the government that they need to provide less money in future years.

Of course the reality is that all agencies would like more funding, so will always work out a way to use up the funds they're given. But giving them all additional funding upfront won't suddenly make them spend the money more appropriately, so it doesn't really achieve much.
