Exactly.

We often see the rich taking their own lives or just doing some self destructive things and that’s because they never had to fight for survival like how the poor did. The poor people had to scrape and work in order to eat and they are not going to throw away the life they worked so hard for.

Unlike the rich who were probably already rich from the moment they were born and did not have to undergo challenges in life. I am aware that this might not be the case for everyone but it certainly is the case for most.

Most rich people that are depressed due to the fact that they were either born into wealth or  did illegal things to attain their wealth, this can give them a sense dissatisfaction about their lives or a feeling of unhappiness, poor people in the other hand learn a lot from life and if they eventually get rich they tend to be happy because they've been through a lot of obstacles and tough times..This might not be the case of everyone though
