Based on Chapter 4, why do saints incarnate when people become overly focused on worldly attachments?

Chapter 4 of the Shri Sai Satcharitra explains that saints incarnate precisely when humanity loses its way in materialism. The text states that when people consider wealth, status, sons, and spouses as the only source of happiness and turn away from the ultimate spiritual goal (Paramartha), saints appear. This happens when people are so obsessed with lust and hunger that they miss the chance for self-upliftment. According to this chapter, the saint's role is to counteract this decay of religion, protect the humble, and reawaken humanity to the possibility of achieving ultimate well-being, which has been lost in the pursuit of transient pleasures.
