We hear so much about "rights", a right to this and a right to that. People say they have a right to decent housing, a right to adequate health care, food, a decent job and, more recently, senior citizens have a right to prescription drugs. In a free society, do people have these rights? Let's look at it.
At least in the standard historical usage of the term, a right is something that exists simultaneously among people. A right confers no obligation on another. For example, the right to free speech is something we all possess. My right to free speech imposes no obligation upon another except that of non-interference. Similarly, I have a right to travel freely. That right imposes no obligation upon another except that of non-interference.
Contrast those rights to the supposed right to decent housing or medical care. Those supposed rights do confer obligations upon others. There is no Santa Claus or Tooth Fairy. If you don't have money to pay for decent housing or medical services, and the government gives you a right to those services, where do you think the money comes from? If you said "From some other American", go to the head of the class. Your right to decent housing and medical care requires that some other American have less of something else, namely diminished rights to his earnings.
