As a result, America’s total tax revenues as a share of national income are among the lowest of all high-income countries, roughly 30%, compared to around 40% in Europe. But 30% of GDP is not enough to cover the needs of health, education, science and technology, social security, infrastructure, and other vital government responsibilities.
正因如此，美国30%的税收收入占国民收入比例在所有高收入国家中排行末尾，而欧洲国家的一般占比在40%左右。 但国内生产总值的30%不够满足医疗、教育、科技、社保、基础设施和其他重要的政府责任需求。
