Lack of financial literacy is one of the reasons for quite massive poverty of the population. The reason is banal - many people do not really understand what money is, do not effectively earn, foolishly spend,... Financial literacy should be given from the 1st grade of school, and the game "Right earning and right spending" - in kindergarten!
In some countries, financial literacy is a government program. Study, for example, how this process is organized in Finland - from the curriculum for the youngest children to courses for adults.
