life is only hard when you are poor, if you are rich enough, everything is easy
Rich is also difficult. They may be lonely, they may be gravely ill, they may be attacked by their life ...
Everyone envies the rich because their lives are much easier. They have less problems than all other people. If to speak about illnesses, the percentage of their morbidity is also smaller, because poor people get sick even because they work hard or in bad conditions. And they also have a lot of other very big problems, with which rich people leave easily enough.
Totally agree with you. As you said, most people envy rich people, because most of things can be bought for money. And not to say that we live in material world, where everything goes around money. More money means easier life, you can buy more healthier food, wear better cloth, go on more different places on the world etc. But money can'y buy everything, real happiness comes from within, and it cant be bought for money. For every person there problems are biggest problems, and that will always be.
