Let's set some ground rules for debate, m'kay?
"Spending on social programs is highly correlated with keeping people in poverty."
Do you have any evidence for this claim? Studies? Data? Facts?
The information I have shows a strong correlation to the opposite: https://upload.wikimedia.org/wikipedia/commons/8/8d/The_Antipoverty_Effect_of_Government_Spending_Vector_Graph.svg
"...because we can print money..."
The government doesn't "print" money to spend, it issues currency. Printing presses and paper money exist these days to accommodate small transactions. When is the last time you bought a car with cash in hand? Or your employer paid you in cash?
I'm making a nit, but it's important to be precise with the terminology. Or you lose credibility.
"You don't understand economics."
Umm... you don't know me, nor what I read, or studied, or what my credentials are. You're making a broad assumption based on a Slashdot comment.
In general, if I don't feel qualified to post in Slashdot I stay quiet. I don't need to spread any more misinformation than there already is.
My statement about public spending is a verifiable fact. There is no theoretical bounds to spending given a fiat currency in the post Bretton Woods era. The gold standard is long gone.
"Is it any wonder the more we pay for welfare, the less likely people are to get off of welfare?"
You raise the example of welfare, which I did not. It is one possible type of social support among many. (Personally I favor the Job Guarantee--provide work to all those who cannot find work.)
To examine this issue in depth you need to look at the causes of poverty. If an individual is unemployed with no prospect for work, welfare can provide sustenance but without unemployment they may never escape from poverty. But if you provide work, public or private, you have a path to independence. For a single parent raising children without support (too common in this day and age), child care and education may be the key. However these have to be accessible, if not by private means, then through social support.
