Medicalization of issues
At Reason Online, Jacob Sullum has an excellent article, "An Epidemic of Meddling".
"What do these four “public health” problems—smoking, playing violent video games, overeating, and gambling—have in common? They’re all things that some people enjoy and other people condemn, attributing to them various bad effects. Sometimes these effects are medical, but they may also be psychological, behavioral, social, or financial. Calling the habits that supposedly lead to these consequences “public health” problems, “epidemics” that need to be controlled, equates choices with diseases, disguises moralizing as science, and casts meddling as medicine. It elevates a collectivist calculus of social welfare above the interests of individuals, who become subject to increasingly intrusive interventions aimed at making them as healthy as they can be, without regard to their own preferences."
