You can find out the advantages and disadvantages of primary school students with pocket money first, and then develop your own ideas accordingly.
For example, pupils at 12 level, especially at 12 level, have no ability to distinguish things from right and wrong at all. They will only blindly follow the crowd and buy some useless items such as snacks. Even if they know, their self-control ability is not good, and they knowingly commit crimes.
Once you have pocket money, you will compare with each other, buy some useless things and waste money. In life, parents have provided us with sufficient material needs, and primary school students don't need pocket money at all.
