According to another study by Cornell's Suzanne Mettler, many Americans don't even realize they're relying upon government services. 53 percent of those who said they're not using a government program borrowed a student loan from the government. 44 percent are on Social Security. 39 percent are on Medicare (reinforcing the imperative: "Keep your government hands off my Medicare!"). 27 percent are on Medicaid. 28 percent are on Disability. 41 percent are receiving veteran's benefits. Again, these are people who also insist they're absolutely not "living off the public tit," to quote Senator Chuck Grassley. But they are.
