While I am sure that's true for a lot of cases, I think you have to look at society and the individual as a whole. Lots of people are homeless or struggling to afford food, and they will never break out of poverty completely even if they manage to improve their situation a little. Add on to that the fact we are killing the planet, each other, and nature all at the same time and I don't think suicide is that unreasonable in some cases. This is especially true for disabled people that can't get jobs or have much quality of life and live on peanuts from the government if anything.
