一位先生发现他雇佣的保姆勤劳、贤惠、可爱,把她娶为妻子。在此之前,他需向保姆支付工资,保姆从事的做饭、清扫房间、照顾老人等活动被计算到GDP中。当保姆变成妻子,她仍然从事同样的劳动,甚至在家务上付出更多,但丈夫不再向她支付报酬,从而这些活动不再增加GDP。 One gentleman found his nanny hired hardworking, virtuous, cute, and marrying her as his wife. Prior to that, he needed to pay his nanny, pay for nannies, clean the room and take care of the elderly. When a nanny becomes a wife, she still does the same work and even pays more for housework, but her husband no longer pays her, so that these activities no longer increase GDP.
