It is not the money that make this problem. It is the value of work that is not the same on this earth. So it is not a new problem that appear just now, it has always existed, but with world realtime information we now know it easiely. You know in some country a man can earn 1 month of work by selling drugs in a day or a week-end. Mindblowing, isn't it? The most important is not the salary you earn but if you can live with it decently and cover your needs, and your family needs, anywhere you live on this earth. I could also say some "privilegied" people can buy big expensive car, villa, boats, and live in some luxury i can't afford with my work. But is it what i want to live, no. I like my life as it is now. Happiness is not linked with money, even if money can sometimes help to reach it. Thanks for this thought sharing.
