Passage Summary: Technology makes the economy grow and jobs easier, but people only like their jobs if they feel the work is hard and they have special talents.

Conclusion: Technological progress tends to undermine the conditions necessary for workers to feel satisfied with their jobs.

Reasoning: Technology makes work easier and specialized skills less necessary, but workers only feel satisfied when they believe their work is difficult and requires rare skills.

Analysis: This argument sets up a direct conflict between the effects of technology and the requirements for human happiness at work. It seems we have managed to create a system that fosters economic prosperity while simultaneously stripping away the very 'difficulty' that makes a job feel rewarding. To complete the argument, look for a statement that bridges this gap by concluding that progress and worker satisfaction are at odds. It is a somber realization that as the machines get smarter, the humans might feel a bit more replaceable.
