I would be careful with that line of thinking. We often envy illusion. We don't truly know that 'those people' are living nearly as wonderful a life as we're inclined to think they are. Further, in my experience, the "perfect life" is always one moment away from "disaster" - be it a health complication, sudden loss, or any of the myriad of ways things go awry. Pain and suffering is not something any of us seems likely to avoid in this life, and inflicting misery upon ourselves due to comparison with what is likely projected fantasy is just one of its many shades.
