In case you haven't been following the news, the recent tax bill was passed under a rule that limited the impact it was allowed to have on the deficit. Therefore, in order to make tax cuts for the rich not cost too much for the bill, they've included changes that remove funding from services or that raise taxes from the not rich. It doesn't matter whether the government as an abstract operates on a balanced budget or not, this particular bill is a (roughly) zero sum one. If you didn't know that, you should really do some more background reading.
