Oh I agree completely. The last coupla presidents didn't realize that government is a business.
Government is not and cannot be treated like a business. It
is the people of the state, made up of elected individuals who the people think will benefit them the most (or in the case of republicans, whoever will hurt the people they don't like the most "CAUSE IF A MAN CAN'T STAND ON HIS OWN HE AIN'T NO MAN, AND THE GUBMINTS SHOULD BE KILLIN DEM QUEEROMOSEXUALS AND FARNERS INSTEAD OF HELPING PEPOLE I TELL YOU WHAT!").
The thing about government spending is, unless you're spending it on another country, or handing it off to people who'll just secret it away in Swiss bank accounts (or worse, invest it in another country, like China), it can't be wasted. The government gets both what it payed one of its citizens to do, and it gets a citizen who now has the income to better participate in the economy, meaning that other citizens are better able to make a living, which means they can better participate in the economy, and so on until it's changed hands and been taxed so many times it's right back in the government's hands. "But if this is true," you ask, "then why do we need the government managing these things at all, if they work so well?" It is because the system is inherently unstable; without oversight by an organization with no profit motive money begins accumulating at the top, where it is either hoarded or spent in foreign countries, hurting the people whose labor produced it in the first place and causing the economy to collapse, as there is no longer anyone to buy things, and thus no profit motive to keeping people employed.
Which is also, by the way, why the government should be providing healthcare to every single one of its citizens, regardless of context. Because no matter what, it's paying Americans to help Americans, so everyone wins except the parasites who found a way to make a disproportionate sum off providing a service that they had to not provide in order to turn a profit ("Pay me money and I'll totally cover your medical bills when you get sick! What? You're sick? Fuck you you're not profitable anymore!"
).
