The best way to come out of poverty is through education. Having education is possible, there are countries where the education is really hard as the parents send their kids to plantations as they weren't able to feed them with their earnings. In such situations we don't have any other go. There are several sayings that people should have the rich mindset, work hard and so many things. Whatever might be, if the time/luck isn't favour of us we aren't gonna be rich forever. I've seen this happen to many people, they hard work but they don't know how to make money. If the same person is educated, surely he would be rich by now.
Hard work with the same nature of job can't bring you to the state that may give you some decent edge over poverty, unlike with proper/higher education where you can explore and can take good opportunities to pick a job that may give you better compensation, though not applied with 3rd world country mostly as there's no way to choose if the availability of job are not competitive enough to earn decently.
I mean even you have good education but the economy can't provide good / high value types of jobs then there's nothing we can do.
Nobody plans to stay poor but the level of being poor is different, some are very deeply poor that have affected their whole family, they have less knowledge about how to get out of the poverty life they live, and some believe that the only way out of poverty is through education, in the end, they are back to where they begin their journey.
Even if one manages to become OKish, maybe find a good job that pays some good amount of salary he will have to cater for his junior brothers and sisters, and sometimes even the whole family, and this will end up becoming a heavy load on him.
Most poverty is from the family themselves, and this will keep affecting the children down to the grandchildren, that's why some say that poverty is passed down to the coming generation.
We witness that most of the time with third world country they are stuck with how their parents/grandparents kind of life and the only options is follow the flow and continue living as it is, we might be able to change this if we will manage to exceed with any limitations that blocking our way, if we are really keen in changing our life and our family's future life then we should find the way.
