Actually it comes from idle funds. Tax rates haven't increased, in fact tax breaks have increased. And because it is borrowed, the consumer and businesses (actually the intermediate banks and financial institutions that handle investments for consumers and businesses) are voluntarily giving the money to the government. The government has to purchase these loans just like anyone else.
If that was true, then the interest rates on government bonds would have to be much higher, as they would have to compete with the private market for returns on investment.
You also try to make the point that government doesn't create wealth, as opposed to a private worker. Well, unless you are actually working on the assembly line or in the engineering office creating the next new thing, you aren't creating wealth. You are just shuffling it around, trying to lose as little of it as possible. A corporate executive is no more wealth creating than a government bureaucrat.
Consumers and industry actually do have a lot of wealth. They simply aren't using enough of it for consumption or investment.
Hey, no fair using real economics to argue against political ideology.
Next you'll be telling me that real biology proves that Young Earth Creationism is false!
