Most human economic activities are influenced by the need for money. But why can anyone not become rich?. What are the reasons why others work hard yet they are still poor? Why can't we print enough money for everyone? Questions like this do appear but there are reasons the answers are opposite.
Did you know that it is virtually impossible for everyone to be wealthy? To understand why, just think for a moment about what it really means to have a lot of money. Resources are not endless. In fact, they become more limited with each passing day. The world population keeps increasing, while Earths resources have stayed the same. A lot more people are clamoring for fewer and fewer resources. As a result, only a few may gain the advantage of having excessive access. Also, if you think about it, if everyone had the same level of income or wealth, then no one would be rich. We all continue to grow richer, but relatively there will always be differences between individuals unless everything was just divided evenly.
This really depends on what you consider wealthy. One of the definitions of being wealthy means having abundance. One of the definitely of abundance is "more than enough". Of course, not everybody can have their own mansion with a hundred acres of land, but I believe that everybody could be wealthy, meaning have more than enough. I am sure that the world has more than enough resources than we need.
To answer the OP, I truly believe that anybody can become rich if they believe in it.
