In the standard historical usage of the term, a “right” is something that exists simultaneously among people. As such, a right imposes 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 noninterference. Similarly, I have a right to travel freely. Again, that right imposes no obligation upon another except that of noninterference.
Contrast those rights to free speech and travel with the supposed rights to medical care and decent housing. Those supposed rights do impose obligations upon others. We see that by recognizing that there is no Santa Claus or tooth fairy. If one does not have money to pay for a medical service or decent housing and the government provides it, where do you think the government gets the money?
If you agree that there is no Santa Claus or tooth fairy and that Congress does not have any resources of its very own, the only way for Congress to give one American something is to first take it from some other American. In other words, if one person has a right to something he did not earn, it requires another person’s not having a right to something he did earn.
