The author never claims that politicians should abandon the goal of increased economic productivity. She just notes that they often overlook the drawbacks of this goal.

The author assumes that what is true of a single corporation is also true of the economy as a whole. Just because increasing productivity in a corporation may reduce employees doesn’t mean that increasing productivity in the economy will increase unemployment.

The author doesn’t generalize about all politicians based on the actions of a few. She just notes that politicians often advocate for increased economic productivity while ignoring its drawbacks. This also seems to be a factual, contextual statement, not an unfair criticism.

The author never assumes that increased economic productivity is always more important than the interests of workers or business owners. She points to unemployment as a drawback of increased productivity, but she never makes any claims about which one is more important.

The author’s argument is vulnerable because she assumes that a drawback of increasing productivity at a single corporation also applies to increasing productivity in the economy as a whole, not because she doesn’t address all potential drawbacks and benefits.
