The sources of people's discontent are largely external: they're the material and social conditions in which they live. Workers' productivity has gone up but they can no longer afford to buy a home or raise a family, while market logic eats away at the fabric of human connection and friendship, and people aren't supposed to feel bad about it? Imagine telling a Victorian child laborer not to "externalize" her discontent to the fact that she's working 12 hours every day in a factory, since she has zero power over it.
