If you gave a poor person the opportunity to become rich through work, would they still decide to stay poor?
When you are being rewarded for hard work it is hard to grasp the concept that some not all people are being rewarded for hard work. Pretty much every entrepreneur falls into that trap. Everything they do can have a direct impact to their bottom line so they work hard and long hours. Meanwhile they wonder why their employees with low wages that are often below planned minimum wage increases do the bare minimum to not get fired. It is pretty obvious. They are going on a silent strike as that is the last drip of their bargaining power. We then get lessons that the poor are poor because of laziness.
I can definitely say that people who are forced to work with capricious scheduling, or those that have to work more than one job just to survive are a lot less likely to do that.
This is how the poor stay poor, and those who are "just broke" become poor. In fact, people who are working are much more likely to engage in other community activities and volunteer.
