The mentality of the people that belongs to different economic classes really varies. We are exposed to different surroundings, hence, we have different ways on how we view life and the circumstances we face each day.

For the people that are naturally born poor, they were used to witnessing things that are perceived as the basis of "reality of life". At a young age, they are introduced to labor to bring some food on their table and to make the ends meet in general. They are conditioned to just accept what kind of status that they have and just dream enough. A dream that is just the bare minimum like having to eat three meals a day, having clothes and slippers to wear, can drink clean water, and other basic human rights. They are conditioned that if they are born poor, then they will die poor. This is because poor people were mindsetted to just accept what they currently have, enclosing them not to dream high because they can barely afford surviving each day.

Meanwhile, naturally born average people are just at the middle. They are exposed to an environment that they can see both worlds. They can do what they want and dream , only as long as they can afford it. They get by without worrying much like poor people worry each day. They can live a comfortable life, but they have to continue working to afford and maintain the lifestyle that they have. Average people's mindset is to work until they achieve the things they want and to soon later on be wealthy enough to achieve the things they want in life. They aren't hindered that much to dream and achieve their aspirations.

On the other hand, naturally born rich are the top of the crop. They can do freely what they want and dream whatever they want and actually achieve it because they have the money. They have safety nets that will catch them if ever their plans will fail the first time they execute it. They aren't pressured much  to work their ass off because they already have what they need and want in the first place. The rich's mindset is often to become even much richer. The rich people are known go be business-minded persons and into investments that could make them generate more income. The money they will use is readily available. They won't worry where to get money to fund their businesses and investments, hence, most of them become multi-millionaire and even billionaire.
