>You are the master of your own destiny. You don’t have to spend time in any way that you don’t choose to, so you might as well spend time taking care of yourself rather than trying to figure out how.
Fundamentally, I don't think this is true. I think free will is a meme.
When you exercise self-possession to change your habits (insofar as you really did it consciously to begin with[0]), you're moving within a predefined space whose boundaries are encoded by myriad factors beyond your control. If, in that space, there's both "succumb to bad habits" and "break bad habits", and you managed to move to "break bad habits", great. But what if the space is only confined to "succumb to bad habits" for some people? That's the fundamental difference here: the conventional concept of agency assumes everyone's decision space is equally voluminous or that they can navigate with equal effort.
Especially disgusting to me is that holders of this view can recline in the comfortable callousness their ignorance or mythology affords them. If someone hasn't improved their circumstances, it's their moral failing, so they deserve their misery.
On the other hand, the callousness that materialist elitism affords you, that someone who can't improve their circumstances deserves their misery, is less comfortable, so it's a better kind of callousness. Many of us couldn't survive without the coddling of our parents and our civilization, and, on average, our civilization is a better place for our participation in it. Given our highly collective world of artifice, why would someone have a worldview that emphasizes some kind of Darwinism? It's a little silly and less palatable than the handwaving of moral virtue, so the end the result is that you're more forgiving of people's failures and proactive in their success.
