Many people in underdeveloped countries works hard meaning that they labor but they are not wealthy individuals because despite their struggling if their work stops their conditions will become worse off. Wealth is after using your skills to earn money then you can give your children quality education, have assets that can last into the future and you can rely on. People can inherit wealth while others have to struggle to make and build wealth, it doesn't come by work or labor alone.
The concept for people who are at a lower economic level is clearly making work a part of themselves because they must be aware that when they work then they will indirectly get wages in the form of money from it in order to survive in the life they are doing now because until now we are even a lot of people who have to die due to their inability to find money and they are clearly required to work to make their lives better even though in the end it can only be sufficient for their daily lives.
This is a form of life's journey because if we come from people with low economic levels we are indirectly required to think about how we can eat and support our families tomorrow and in the end money is always a problem that cannot be solved so working is a mandatory thing to support it.
