Unintended Consequences
You know about some of the perverse things that happen in life – people are forced to wear seatbelts, so they feel safer, so they drive faster, which results in more accidents. People get immunized for diseases, so they feel safer, and hang out with sick people more, and contract other illnesses. People have low-deductible health insurance, so they go to the doctor more for minor issues, get lots of expensive tests, and increase the overall money spent on health care.
