Think about how stuff works in the real world.

If you buy something, it has an exact price (plus tax),

And you usually get exact change, down to the penny.

But when it comes to government spending, they just add as many 000’s as they think they need, and they don’t ask for the change.

Do you think we will get any change back from Pakistan, after they finish up teaching gender studies ?

When you pay taxes, you owe an exact amount, down to the penny, but when they spend taxes, they just round it up to the nearest billion.
