"Ninguna sociedad puede prosperar y ser feliz si la gran mayoría de sus miembros son pobres y miserables."

Simplified Meaning:

For a society to truly be successful and joyful, most of its people need to live well and feel happy. If a large number of people are struggling with poverty and sadness, the community as a whole will suffer. Imagine a small town where only a few families are wealthy, but many others can't afford basic needs like food, housing, or healthcare. The wealthy families might be comfortable, but the overall mood of the town will be gloomy. People will lack opportunities, there could be more crime, and those who are poor will have a hard time improving their situation. To create a better community, everyone needs to have fair chances to succeed and access resources that help them live decent lives. When people are supported and can thrive, the entire society becomes a better place for everyone.
