I see cognitive behavioral therapy as being a process that includes the self awareness part of mindfulness at least. The acceptance part of mindfulness, accepting your unpleasant thoughts without judgement, could be viewed as looking past your justifiable concerns surrounding the negative aspects of your experience as a working person, but I prefer to see it as disarming your thoughts rather than disregarding them. Nothing about mindfulness based therapy suggests we should change our values, rather that we should not torture ourselves with obsessive and negative thinking.

I do think that mindfulness can be cynically "hocked" to working people to get them to ignore the inequities of capitalist society, but it can't actually get you to believe that you're not experiencing them. I also believe that mindfulness has a place in a post revolutionary society.
