I do not agree with your statement, all the facts of life are not as you expected because the rich will not be eternally rich or vice versa that the poor will not be eternally poor in this world, throughout the journey of life until now that the wheel of life has always turned and some poor people have become rich because his hard work efforts have improved the economy for the better, life is very dynamic, so try to increase your finances until you are on the list of rich people, it will motivate other people to get the same opportunities.
What about statistics, which part of rich becomes poor and which part of poor becomes rich? The problem with migrating from one group into another is in different way of thinking: that's why some people become rich and go through bankruptcy multiple times and others always stay poor and struggle for food. And if you are extremely cautions because are afraid that there could be nothing to eat tomorrow you'll hardly take a loan to start your own small business, because you probably even don't know how to do it. An old film "The Millionairess" of 1960 shows this in a comedy way but it looks rather correct.
