"The rich also cry," they are humans like every other people but the only difference is that they have money and by virtue, they would have power. These two alone have helped them in solving the majority of human problems/concerns that cause other problems. If people have money, they can be happy, have a healthy living, have access to the best healthcare facility, rule in their own little way and most importantly have financial freedom. This makes the living of the rich more comfortable for them which is the only thing they are better with compared to the poor. Every other thing are same with every financial class so long as they are living souls.
Rich do not have terrible lives unless a terrible thing happens to them. I mean you can be the richest person in the world, but if your loved one battling cancer and eventually dies, you are going to be miserable, or you could be the one battling it and lose, look at Steve Jobs for example.
It's obvious we are going to see these type of bad situations in everyone's life, even though rich could afford better healthcare, even the best will not allow you to survive if you are not going to survive, give you a better chance to survive but still a risk. Whereas, if you end up with no sickness or anything like that, if you are not at that part of your life, then you are going to end up being much happier than someone who is poor.
Sadness of all humans equal to each, but aside from those, regular days are much better. A rich person who is not happy, must have sickness or something in the family, OR they are morons who do not know how to use money to be happy, those are the only two options.
