I don't personally have a problem with people making money from Mindfulness - I'm myself studying to be an MBSR teacher and ultimately I may well find myself being paid for this. I pay for Sam Harris' Waking Up app. I pay for retreats (I'm going on a 5 day one tomorrow as it happens!) - none of this strikes me as problematic.
What is problematic for me is the misunderstanding that this new industry (actually, as someone else says below, it's not new, it's just "New Age", only...newer) IS the practice that underlies it. It isn't. And further to this, nothing is going to save anything without work and practice and fluidity and understanding, least of all meditative practice. I have sympathy with the view that this modern approach has found itself in the company of rich Westerners looking or boardrooms or consultants all looking either to find meaning or to make loads of cash. But the misunderstanding about the practice itself is just plain wrong.
In the world of mindfulness and meditative practice that I inhabit, it is compassion and understanding and - totally - that outward looking view which is at the core. It is SO far from being a narcissistic, inward-looking thing. A fundamental principle which runs throughout this practice circles around Metta[1] - and what's been interesting to me as a practitioner is how uncomfortable this can be! We're so used to being insular and inward looking and all the things you cite in your reply that to be faced with an outward-looking, compassion based set of principles can feel really quite exposing and strange.
Does this solve inequality? No, of course not. Do I come at this from a privileged and relatively wealthy white male point of view? Yes. But we'd accept, wouldn't we, that (say) fitness, maintaining a good weight, working less, eating well, having more time with family, etc. are all "good things" without being shot down for being elitist?
The question for me is: Does a more inclusive, compassionate, considered world view help people to help others in some small way? I hope so. In large part that's exactly why I do this practice.
