Proponents of HSAs believe that they are an important reform that will help reduce the growth of health care costs and increase the efficiency of the health care system. According to proponents, HSAs encourage saving for future health care expenses, allow the patient to receive needed care without a gatekeeper to determine what benefits are allowed, and make consumers more responsible for their own health care choices through the required high-deductible health plan. Opponents observe that the structure of HSAs complicates the decision of whether to obtain medical treatment, by setting it against tax liability and retirement-saving goals. There is also debate about consumer satisfaction with these plans.
