This little boy has definitely experienced the difficulty of earning money and the hardships of life. In fact, I personally recognize his parents' approach to education, because by letting the child earn his own money and letting him feel how difficult it is to live in society, he may also have a concept of money from now on. Take the example of this little boy who earned $34 by picking up scraps, he may use this $34 as a yardstick when he wants to buy any item later on.
He will know that if the price is more than $34, then he will think that he may have to work harder for it, if he weighs it against his own labor. Of course if that price is under $34 then he might think it's probably a level he can live with. In fact, if he is allowed to earn money in this way, he will be able to feel the difficulty of life as well as the hard work of earning money.
Nowadays, a lot of children at home are actually in a privileged situation, usually have any need to tell their parents, basically their parents will meet or have any desired things. Even if the parents temporarily do not agree, but also through other ways to let the parents to fulfill their own wishes, because they want anything can easily get, so that for the money will not have too much concept.
Some parents, like this one, let their children experience the hard work of earning a living by letting them experience it for themselves, which I think is actually very helpful for the children's development. Because in this process, they can y feel that earning money is not an easy thing, and when they want anything in the future, they will also make an assessment based on the money they earn. Within a week's work to pick up waste only earned 34 dollars, in fact, for the child, will leave a very deep impression on them, for money will also have a clearer perception.
