If, when defending your support for Donald Trump, and your response is,
"But but but... HILLARY!!!", then you lost the argument before you even began.
If it is taxed away from someone who would have sunk the money into the near-black hole that we call the stock market, and if it is then spent on something that we need, like raising the height of a bridge so that big trucks can utilize the road, then the government spending may result in more growth than if it wasn't taxed away.
However, I don't generally advocate higher taxes, I actually think we should lower taxes on the worker/consumer class in order to increase demand.
This is one the things that so perfectly illustrates one of the biggest differences between liberals and conservatives. Liberals tend towards short term thinking and conservatives tend towards long term thinking. Both have their advantages and even necessities, but short term thinking always leads to more problems than it solves.
Our nation has not always lived up to its ideals, yet those ideals have never ceased to guide us. They expose our flaws, and lead us to mend them. We are the beneficiaries of the work of the generations before us and it is each generation's responsibility to continue that work. - Laura Bush
Now to the meat of your question: does government spending produce economic growth. And as others have mentioned, the answer is that it depends. Up to the level of government revenue, the effect is probably a small reductionto a very small increase in growth(it more than likely varies by year and how the money is spent). However, the government does not spend to the level of revenue, it spends beyond that level. And that deficit spending also goes into the economy, creating more growth. So the end effect is an increase in growth.
We can even measure the effect of government spending on particular items to growth. Here is an example(first google return, not commenting on the actual accuracy of the numbers themselves, just using link to illustrate concept): Infrastructure Economic Multiplier - Business Insider. The article states that the normal multiplier for government spending is 0.5 to 1.5, meaning that for each dollar spent, it grows the economy between 0.50 dollars to 1.5 dollars. The article also states that infrastructure spending(roads and such) reach a multiplier of about 2, or 2 dollars growth for each dollar spent. While I do not endorse the actual numbers(though they could very well be right, I simply do not have enough knowledge to say they are right or wrong), the concept is pretty solid.
“I think if Thomas Jefferson were looking down, the author of the Bill of Rights, on what’s being proposed here, he’d agree with it. He would agree that the First Amendment cannot be absolute.” - Chuck Schumer (D). Yet, Madison and Mason wrote the Bill of Rights, according to Sheila Jackson Lee, 400 years ago. Yup, it's a fact.
“If we must have an enemy at the head of Government, let it be one whom we can oppose, and for whom we are not responsible, who will not involve our party in the disgrace of his foolish and bad measures.”

We have had a national debt every year since 1838 and every year before 1835.
Every country in the world except for 7 have federal debts, and most of those seven are city-states or not much larger than city-states.
Federal debt is one of the things that stablizes countries money supply.
