D
Politicians often advocate increased overall economic productivity while ignoring its drawbacks. For example, attempting to increase the productivity of a corporation means attempting to increase its profitability, which typically leads to a reduction in the number of workers employed by that corporation. Thus, attempting to increase productivity in the economy as a whole may benefit business owners, but will increase the number of unemployed workers. The reasoning in the argument is most vulnerable to criticism on the grounds that the argument
A: unfairly criticizes politicians in general on the basis of the actions of a few who are unwilling to consider the drawbacks of attempting to increase productivity
B: fails to address all potential drawbacks and benefits of attempting to increase productivity at a single corporation
C: presumes, without providing justification, that increased unemployment is sufficient reason to abandon increased productivity as an economic goal
D: fails to justify its presumption that attempting to increase productivity in the economy as a whole would produce results similar to those produced by attempting to increase productivity in a single corporation
