hard works doesn't guarantee that you will become rich because if handworkers become rich then Labor will be the richest person all over the world. Sometimes lazy people get the reward because of knowledge and hard workers remains in the same state.
Hard work by relying on the physicality of our own bodies will obviously not make us rich, especially if it is not accompanied by brilliant ideas that can inspire many people. Now hard work and smart work must both be accompanied if someone wants to achieve wealth in his life because being smart at work is part of a person's intelligence in seeing an opportunity that exists, while hard work is part of his will to rise from laziness in his life. So this must be equally balanced because success does not belong to those who are smart but success belongs to those who want to work hard and be smart.
According to my opinion poor are more hard working than wealthy people. Other thing is that some people become successful because they have strong support from their parents and strong foundation of wealth from their ancestor which make them more wealthy.
It was logical, but their ancestors or parents were also poor and struggled before the next generation in their family was born. This means that those who rely on the foundation of success from their ancestors or their own parents is a success that has been inherited and has been found by their parents in the past, not the result of success that they got themselves through their own hands or thoughts.
And I think it's also quite natural for them because they have a place to hope, but for those who are still poor and continue to work diligently according to the plans they have made themselves will also be successful in the end. Even though they have to go through a long way because they have no foundation or place to hope as experienced by those who are rich.
