if they'd thought to invest
Investment comes with a risk. The middle class doesn’t understands how investment works or even how or where to invest, or the middle class may not want to take the risk and feel it safer to save but given the opportunity, they may invest. But even when they do, most will never get rich. Sure, the investment can make people more money but not tons of it because you need to know what your are doing, it is risky and it ain’t easy. Regarding the poor, they live for today and it is easy to spend free money on 500 dollar sneakers made in Asia. That is the nature of the beast and why the poor will always be poor. Even with opportunities, they choose the life from hand to mouth because that is the way some people are. The rich have extra money and can afford to take a chance on investment or they just have extra money that they put to work for them whereas the middle class doesn’t have all that extra money that they can dedicate to investment. But everything considered it depends on the type of individual whether they have that drive to invest.
