I'd say having a "stable middle-class" parent is the worst starting point to become rich. It's a sure way to become a similarly boring middle-middle class person - that is, a strictly conformist, risk-averse, boot-licking serf. Kid of a rich person will probably become rich because they inherit cash. Kid of a poor person may become rich because they are ready to take risk and usually have good social skills. That, or they may die trying or end up in prison... But there's no good pathway to become rich if you come from a boring middle-middle-class. Too little money for elite uni or other ways to "hack" it, too little money for risk taking ("starting a startup because you always have something to fall back on"), and inherited attitude against risk-taking. Dead end. You just take up a mediocre white collar job and count years till retirement.
