Just to expand on what you're saying, it wouldn't function properly at the very least and you can look here in Brasil for confirmation of that.

After the 2015 coup of Dilma with her impeachment, we saw Michel Temer take her place and with him came the implementation of a "spending roof" where we can't spend more than the predetermined amount (the roof) to keep the economy in a superávitary state, of course there are specific situations where the government can spend above that, but as rule of thumb it can't go over. Because of that our economy growth is now capped (I don't remember the exact percentage, but it's a very low single digit), we can't properly develop infrastructure, our social nets gets fucked, in particular you can look at SUS (our public health system) where it continues to go underfunded and attacked at every turn. As another example, you can also look into Correios (our national mail delivery system) which has seen mass attacks and has been underfunded to both reduce spending and create the conditions for it's privatization, which hopefully failed so far.
