So we shouldn’t try? Just let the budget expand forever?
If I were king for a day I’d make it so the government agencies somewhat regularly (say, every 5-10 years or so) would be subjected to significant budget cuts (without stopping with the yearly increases they already get). That would make it similar to many businesses, and force the management at the agencies to actually figure out how to do things efficiently.
Of course, people would whine incessantly as we saw with DOGE the second those cuts hit a program where the media can cause an uproar about hungry children or health programs or whatever.
