I'm assuming this is some kind of jab at the general propensity of psychiatry to classify most things as disorders, rather than a serious proposal. If anything, I think the problem has gotten worse since this was published. (Then again, maybe happiness has also gotten more rare since 1992?)
We went from 3% on anti-depressants in 1992 to 13%. Lots more are trying to induce happiness without an external change of circumstance or internal perspective.
