High price does not equal high quality products and services, this certainly applies to US made products and foreign products sold in US. If you use your US$ and live outside US, your buying power increases by 3-7x comparing to buying identical products and services inside the US territories. As a result, US GDP is highly inflated. 高價格並不等於高品質的產品和服務，這當然適用於美國製造的產品和在美國銷售的外國產品。如果您使用美元並居住在美國境外，與在美國境內購買相同產品和服務相比，您的購買力將增加 3-7 倍。因此，美國的國民生產毛額是被嚴重誇大.
