Well we have different problem in life, some of the poor people might think that the wealthy people have less problems because they can eat what they want they have a lot of money to enjoy life and buy all thier needs, but the truth is they also have a problem, only fool can have no problem because they don't think about the future.
Every life is sure to have its own. So of problems and will not be the same. So, people who have money can be sure to have the same problems as those who do not have money, but the problems are always different and usually according to the circumstances of the person.
Now it remains whether they can solve the problem well. I agree that those who do not have problems are those who do not want to think, and usually those people are not worthy of being called smart.
"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.
