I think that the major advantage of being wealthy is the economic stability that the money can bring us. On the other hand, the main disadvantage of being rich is that the way of life turns into a kind of bubble, free of the real problems of most of the people.
In what concerns to the pros of have a lot of money, first of all, I think that in this world that it’s so material, the money can brings lot of stability to live peacefully. Secondly, having money can be so good if we do periodically donations to all kinds of foundations.
However, being millionaire also has cons. One disadvantage, as I recently named, involves the “fake life” that we may live if we start to forget that poverty and hunger are outside of that bubble that the money creates allowing us to live surrounded of all kind of material things. In addition to this, being wealthy also can makes us dissatisfied because we enter in an endless circle of needs; because when we achieved our needs, we immediatly continue to needing more and more.
To sum up, I think that the pros and cons of being wealthy are going to depends on the way that we as human beings knows how to managed -in a good way- the fact of have more money than the rest.
