I assume you're talking about the Federal Insurance program (Medicare, Medicaid, and Social Security). Because a lot of people on the left want to spend more money on those.
Those are some of the most functional, most loved programs in this country. Social security is our sovereign wealth fund, and only comes into crisis when it is tapped for purposes it wasn't intended for. Medicaid/care allows a profitable, private health insurance industry to exist. These programs basically saved capitalism in this country, be grateful.
