This matters because, as the great economist Arthur Okun argued, reducing unemployment by two percentage points would increase output by 2%-6%, or $0.5-1.5 trillion dollars in the case of America. Even for a rich country, that is a lot of money.
这很重要，正像伟大的经济学家Arthur Okun所说的，在美国把失业率降低两个百分点会把产量增加2%到6%，或者说5千亿到1万5千亿美元。即便对一个富有的国家来说，这也是很大一笔钱。用它可以使美国未来75到100年间的社会保障体系都高枕无忧。甚至它可以支付打一场像伊拉克战争那样的费用！
