I agree. I think happiness and “well-being” are not actual realities. There is only the pursuit of happiness. And that pursuit can be manipulated for financial gain. I think the very best you can achieve is being a child or failing that contentedness and absence of suffering. Otherwise loss and grief will strip away any possibility of happiness. The only fleeting happiness/joy I often see in myself or other adults is in nostalgia - and that’s pure manipulation.
It certainly could be. There’s the old Greek myth of Pandora’s box - the last entity to emerge is ‘hope’. Is that the worst monster or greatest gift to humanity? I feel like I fall in the former camp. But that’s OK - I still move forward in life and engage in the pursuit of happiness.
