Why is it that the rich get richer and the poor stay poor?

The main reason to why the rich get richer and the poor stay poor is because of our human nature of selfishness. Ever since historic times, there have been the 'superior' population and then the 'inferior' population, the colonizers and the colonized respectively. The colonizers had power over the others and could do whatever they want to exploit the locals. Having to experience the ability of power, the superiors are not able to give up what they have, even if this means helping to make the others' life better; they feel no obligation in anyway to do so, because the others are 'inferior'. From this, disparity is created.

Contemporarily, the rich such as the owners of big multinational corporations may own more than double of that of the poor, they still are not willing to forgo their success. We may see powerful and wealthy people like Bill Gates as philanthropists,donating to the needies, but it still does not help the poor to rack up their statuses. The money isn't enough to provide a perfect environment like they themselves grew up in, education, food, shelter, family and more. Furthermore, the money that these wealthy people donate may be just a small portion of their total wealth because they want to keep their luxurious life.

It is impossible for one to be truly altruistic and forgo all their wealth because it is true that some had worked harder than others. It is also that people were born into families, and if the family doesn't have the required resources, it is extremely hard for one to climb up the social status. Such as that if I were born into a family without any access to education, I wouldn't be able to get a decent job in the future, which leads me back to the same life of lacking necessities because I don't earn enough to go further.
