I used to work in hospitality (a weird mix of tech + hospitality, if you know you know) and can absolutely confirm this.
Everyone in housekeeping was an immigrant. Most were probably illegal, but I never confirmed this.
The drugs are all made by what, 3 corporations? If they just claim suicidal thoughts and depression are a side effect of every drug then the drugs that DO have that as an effect (SSRIs) will never be the subject of a lawsuit over it.
Serious depression causes you to stop taking actions at all. Forget the term. Executive dysfunction?
Anyway. If you're really fucking depressed, you get too depressed to even kill yourself. The shitty thing being that on the way out of that pit you pass through the "still fucking depressed, but have enough energy to do something about it now" phase, which is when people kill themselves.
Unironically getting on antidepressants, if you actually really really fucking need them, kills people. Because it helps, just enough, to give them enough get up and go to get up and die.
