Acharya Prashant explains that welfare or wellness is fundamentally an internal experience within the subject, regardless of whether the object of that experience is external or material. While material prosperity is necessary up to a certain threshold to ensure basic needs like food and shelter, beyond that point, external growth does not lead to an increase in internal wellness. He notes that many developed nations have already exceeded this threshold, resulting in a saturation where further material accumulation fails to improve human well-being and instead causes catastrophic environmental damage.
