I applaud the conflation of religion and capitalism as both merely being belief systems. I tend to call any and all belief systems "religions" regardless of their relationship to the so called "sacred", and I wish more people would join me in this.

However, I would also suggest that the only thing that gives life meaning (and therefore, the only thing that we ought to reserve being called "sacred") is the capacity for people and other sentient beings to experience feelings of happiness or suffering - which you might call our well-being. Everything else that humans have ever called "sacred" is a fabrication.

Obviously, capitalism has not done a good job of fostering well-being on a global scale. And although we might well say that greed is the engine that drives capitalism, I would argue that we nevertheless still judge the success of capitalism based on how well it serves people’s well-being. Which is to say, we still judge capitalism based on its ability to fulfill our sacred needs. And that is still a step above most traditional religions, which judge their success by metrics that are totally fabricated, like the satisfaction of a deity. And to me, that is truly profane.
