I disagree with Marx about a lot of things, but I do think that this theory makes a lot of sense. As we become increasingly mechanistic in our work, we feel less agency. Less control. Less attachment to the work. We stop caring about the product.
You can pay people to care, for agile, but ultimately the alienation wins. The solution? I'm not sure! Probably several possible things, not least of which is probably work that's focused on building one's community and helping meet their needs.
