Why are some people more capable of enduring suffering and misfortune than others?

I have no idea if this deal with religion or not but, I have always believed that not everyone has the same life and people go through things like suffering and loss so they can help others when they see it happen to other people or they end up keeping their sorrow to themselves and not everyone can be born in the same class so it can bring awareness to people. It's like they want high class people to appreciate they have a better life than the middle class or lower class people even.  

Explanation:

I hope this makes sense and helps you

in this text, paine use the word “ye” several times in order to  capture  the  attention of the colonists who   haven't understand the   importance and urgency of his cause. the word "ye" that is the plural of   "thou" is used to call the colonists attention and make the fight for the cause.

yes you could be a life guard if that the question.
