2. (15) Matching theory to the real world and critiquing our current theoretical models. The models that we studied in class so far relied on the following three assumptions: a) (5) When taxes change, they change by the same amount for all consumers b) (5) All government debt is completely paid off within the lifetime of the people alive when the debt was issued c) (5) Wages are perfectly flexible and can increase and decrease freely with- out any limitations. For each of the three assumptions above, give one example when the assumption is violated if we are trying to describe the U.S. economy. You do not need to elaborate what happens when each assumption does not hold, you need to provide an example why this assumption is not always realistic. This is an open-ended question with many possible answers
