A somewhat recent study showed that more than 25% of people who receive food stamps don't believe they receive any assistance from the government.  Almost 40% of Medicare recipients are in the same boat, as well as almost 30% with Social Security. 

Lumped into those statistics are people who don't believe their mortgage interest tax deduction is a government benefit (60%) and people who receive federally-backed student loans (53%).  I don't think real-cash-money from the government in the form of food stamps and health care should be in the same category as paying lower taxes and receiving low interest rates.  Here's a good take on that: 
A 529 program is not a government program like food stamps, it is the absence of a government tax ... People who use 529 programs and who think that they have not used a government social program are not willfully ignorant, they are demonstrating a healthy if fading appreciation of the distinction between civil society and government.  What Rampell et al. implicitly imagine is that the natural state is slavery and any departure from that state a government benefit. Thus, if the government taxes your saving for a college education less than your other savings, you should be grateful for how government has benefited you and your children. And if the government doesn’t jail you today, you should be grateful for how government has granted you the benefit of liberty. This is the attitude of a serf not an American.
