You are an urban policy analyst reviewing a consultant's report on your city's housing affordability crisis. The report proposes a solution based on the assumption that household income is distributed symmetrically, with most residents clustered in a large 'middle-income' group. The recommended policy is to subsidize the construction of moderately-priced housing targeted at this group. However, your own data reveals that the city's income distribution is actually highly skewed: a very large number of households have low incomes, while a very small number of households have extremely high incomes. Based on this new information, critically evaluate the consultant's proposed policy. What is the primary flaw in their reasoning, and why is their solution likely to be ineffective?
