This study investigates the implications of systemic problems on policy-making and the associated financial burdens placed on specific consumer groups, particularly within the low- to middle-income brackets and small to medium-sized businesses. By examining the policies passed ostensibly to address societal issues, this analysis highlights a recurring pattern: well-intentioned or performative policy decisions often impose additional costs on society without adequately measurable standards for accountability or effectiveness. For instance, increased sales and property taxes, along with rising rent costs, create additional financial strain for consumers, small business owners, and renters, ultimately diminishing their economic resilience and heightening their dependency on governmental aid. The lack of clear Key Performance Indicators (KPIs) or Objectives and Key Results (OKRs) to measure success contributes to a feedback loop where unproductive programs remain unchecked, furthering the original problem and creating a costly cycle of dependency and program expansion. The analysis outlines how, due to financial strain, businesses close or relocate, resulting in job market contraction and increased competition, leaving vulnerable populations with fewer employment opportunities. For populations already economically disadvantaged, especially those lacking adequate resources or education, this dynamic disproportionately impacts mental health and escalates reliance on maladaptive coping mechanisms. Rising financial and emotional distress manifest through heightened anxiety, substance misuse, and deteriorating family stability, adding pressure to public health systems and amplifying the original issues. This cycle emphasizes the significance of comprehensively evaluating the socioeconomic impacts of policies, particularly when metrics of success are absent or poorly defined.

A societal issue has arisen, creating a perceived need for government intervention. In response, politicians—often presenting their actions as compassion-driven—enact policies intended to address this issue. However, as the political environment evolves, additional policies are frequently introduced, sometimes beyond what is necessary. This can lead to an excessive policy landscape that, while well-intentioned, may inadvertently exacerbate the problem.

Fizemos uma breve análise utilizando o pacote Caret, verificando a acurácia, sensibilidade, especificidade. E para além disso fizemos um gráfico de correlação a matriz de confiança e a curva ROC. Para essas análises usamos o banco de dados Pinguins estendido. Ministrado na aula de Tópicos Espaciais de Estatística.
