So, you disagree that suicidal thoughts stem from depression and you think that the government somehow invented this in order to control people?
The desire to die may stem from depression in some cases, and may stem from a reasoned analysis of one’s future prospects in other cases, and may stem from unusual religious beliefs in yet other cases. Blanket claims that the desire to die is always the result of depression are unfounded. Furthermore, some people have suffered all their lives with severe clinical depression, and have tried every treatment known to modern medical-psychiatric science without relief, and have made a reasoned decision that they do not wish to continue living in this condition and that the prospects of new medical breakthroughs in the near future are too small to be worth suffering further in hopes of getting some benefit from them. The government has no right to force them suffer further, even if they lack the capacity to kill themselves (i.e. severely physically disabled or in a secure psych ward with anti-suicide measure in place).
Take a look at how government is funneling more and more money into the medical profession and related businesses, with more and more being spent on treatments not wanted by the patients in question. There’s plenty of financial incentive on both sides (government and the medical industry) to legally mandate forced care and forced suicide prevention). The ideas that there’s a government solution for every problem and that there’s a medical solution for every problem are becoming progressively less distinguishable from each other.
