I honestly concur with that statement!! "If you are born poor! it is difficult to change one's life for the better" . However, the difficulty is not the same as impossible, which is why most middle-class opportunist usually finds their way into the richness the lower class grinds hard enough to meet up with middle-class riches, and their children pick up the pace from where they left off. If you check the number of hard-working people in society, most of them are from middle-class rich families because the parents automatically transfer that level of aggressiveness of being rich into them and they sometimes meet up and turn the situation of the family around, but if you happen to come from another poor linage !! then you will have to work extra hard to set the stage for the next generation to come!!! so the circle continues. which is why the poor keeps getting poorer and the rich keep getting richer but the statement will never apply to middle-class people because they eventually get richer
Even poor parents can raise a successful child by explaining the importance of education and the value of time that is sometimes wasted on unnecessary things. However, poverty is the acceptance of one's situation and agreement with it. Agree; we know many cases when successful professionals in one or another specialty come from poor families. I often read the expression here on the forum: It is not scary to be born poor; it is scary to remain so as an adult.
In most cases, poor people do not know a better life only because they do not see anything better but are content with little.
