They are looking for peace, and in their view death can offer that
Depression is a very prevalent disease in today's society and is very difficult to treat.
It is difficult to bring back a person who thinks that the only way to peace is death.
As tht said "People in places where the level of wealth is low say, "I haven't enjoyed life yet, I have to live" and don't want to die.", probably makes sense.
The poor hope for the rest of their lives that they will live better someday, while the richer ones quickly realize that they won't, so they quickly surrender to complete depression.
We now have a friend who had a beautiful life, part of it she spent in Sydney, where her son now lives with his family, and she is currently in a psychiatric institution. Severe depression, and my sister, who had a catastrophic hard life (she was fatherless as a child, worked two jobs for years...), but she doesn't give up.
But whether rich or poor, the one who is depressed and thinks about finding peace, can find it in another place than death.
If he does not have the support of his family and environment, he can leave his previous way of life and find peace in nature, by the sea, lake, mountain, forest. He can engage in charity work, to find a purpose in another place, if he does not find it in his current life... To spend the values he has acquired in his life in any place for life, not for death.
One of the potential problems we now have is comparing the conditions someone has to another, as if the people themselves are one to one.
For instance, One person can run up a flight of stairs, so why can't another person in a wheelchair? People go, that is obvious, they are in a wheelchair, their body can't do it - but the brain is also a physical organ and part of the body - what if the brain can't do it?
This is an assumption, isn't it? Maybe it is true, but maybe it is not. But regardless, for the person in the situation that can't see an alternative, it is irrelevant what other options there might be.
For example, you also mentioned euthanasia as an option, but have you ever looked at the cost of it? It is above most people's capabilities.
I mentioned euthanasia as an option in the case of a terminally ill person, towards the end, which would be very painful for the patient.
I never had the need (thank God) to inquire about the price of it, and I had nowhere, since it is not legal in my country.
I believe that there is more of a question of ethics and morality than price.
But yes, someone who has no money, how could he even think of such a thing...
He would die in the most excruciating pain or be drugged with painkillers.
As you wrote, if a person sees no other path than suicide to find his peace, I agree, it is very difficult to divert him from that path.
But such a person, if he shows the presence of depression, should be noticed and talked to.
Do not turn your head.
Because often they want to be noticed, asked, they want company and attention.
This is also the case with this friend of ours, who found attention in the presence of my sister. And my sister will do everything to get her out of depression and not to think of suicide.
