It's quite complicated as being wealthy also means their parents had indirectly educated them financially since childhood and they have further invested into making connections, so even if they fail, they can easily bounce back. People trapped in poverty need more than just sowing little seeds or financial intelligence, since their life is already "predetermined" due to their environment until a strong outside force acts on their circumstances... which "financially literate" people don't believe in.
