This depends on your definition of the concept of "poor" because this concept has become more complex and developed with technological, cultural and economic progress in relation to the capabilities of each nation. In the past, the ignorant was the one who could not read and write, while the same concept in our time has come to mean those who do not know English and do not use computers. It is the same development in the concept of the poor, because if the poor of yesterday were those who could not find food and were unable to provide the basics of life, then today they are joined by all those who are unable to keep up with the average lifestyle in their countries; for example, those who do not own a private car in some economies can be considered poor.
