I have heard many people say this and I have done my observations. Problems that rich people have are easily solvable. The way people say you won't have peace of mind or will have a lot of stress, etc. It's all bullsh*t because that's not how it works if you know how to manage things. Those who don't have money or enough money to live a good life will have way more problems than the rich. If someone says that they don't have money but have peace of mind, they are lying, and if they act happy, they are basically trying to convince themselves and others that their life is perfect but it is not.
It's a common misconception that wealth can't buy you everything, the truth is, it can. We are not talking about life here, but other than that, there is nothing that you can't get if you have wealth, you name it, and it's yours, even relationships these days are built after seeing the status of a person.
The bottom line is, money is important. The era we live in, the way this world has become, no matter what some people might say, money is the most important thing, and if you are generally good in managing things, having wealth doesn't make you have a stressful life, it makes things easier for you.
Is not how you think, this thing about having problems is just heavy for the rich people more than it is for the poor. Now look at it this way, a poor man only have to think of feeding his family taking care of the children fees and some other bills, and everybody knows that individual doesn't have much and he's not close to being a rich or wealthy man and the poor man will be comfortable with what he have with him and his family living in peace and love/happiness.
But the rich can't make some move that the poor make, the rich can't walk alone without body guards and the rich is always a target to kidnappers or some of those people he has used his money to oppress, too much thinking for his safety and all that, ones you're wealthy you have so much to thinking of compared to the poor people, they live like not is there to think of not that they don't think but is not the same as the rich men, still carry another investigation and observe again.
