That only works with a static scoring - if you literally believe that all money not seized by government disappears. If you can stretch your mind to believe that some of this money will be spent by individuals, then that money will generate corporate profits and paychecks, some of which will be returned in taxes. If you can believe that some of that money will be saved, where others may borrow it and create growth in the economy (i.e. buying products and hiring workers), then that money will generate corporate profits and paychecks, some of which will be returned in taxes. If you can believe that some of that money will be invested, funding corporate growth and spurring purchasing of products and hiring workers, then that money will generate corporate profits and paychecks, some of which will be returned in taxes. If conversely you believe that $4 trillion will be stuffed into mattresses over the next ten years, then your statement would be true.
By your reasoning, government should simply triple taxes and everything would be fine, since by a static scoring government may take any amount of money from the public without changing their spending habits. By that standard, North Korea would be the wealthiest nation on Earth.
