>Lots of persons seem to be "uninterested in serious personal development"

I don't think being uninterested in disengaging from consumer capitalism is akin to being uninterested in personal development. Being pro-mindfullness and anti-consumer is valid, but so is being pro-consumer and uninterested in mindfullness (because they are chasing other goals, which could be considered part of personal development). The mistake the author makes is assuming their goals are the best way to go, and then prescribing solutions for that.

The author's point of view is actually just fairly narrow. There is nothing wrong with their view, or the ideas they suggest for improving one's life if you share his perspective. But a lot of people simply don't share that view. As a counterpoint, some people (not mine) think the highest goal in life is to work as much as possible. They will do so, and probably consume a lot in order to maximise their time working. That goal and lifestyle might seem unsavoury to me or you, but it is another way to personal development: that you can, personally, be a really good worker.
