对您这种人，我有那必要吗？我很赞赏您的务实精神，能会用GOOGLE查数据是不错的，但您也得知道怎么解读数据吧？1939美国名义GDP俩千亿和美国国会拨款四千亿有冲突吗？

数据来自 “Where’s the Money Coming from? Problems of Postwar Finance”， Stuart Chase （1943）原文如下：

In 1939, the United States Congress declined to appropriate $4 billions for highways, conservation, hospitals, freight cars, in the bitterly contested “lend-spend” bill. It was widely held that the bill would lead to ruin and national bankruptcy. Yet since the fall of France in 1940, Congress has appropriated almost $300 billions for armaments – seventy-five times as much as the lend-spend bill – and a large fraction of it has already gone into tanks and guns. Far from being ruined, our national vitality has never been more vigorous, and great financial moguls assure us that we shall be able to swing the national debt.

Where did the money come from?

我今天刚看到BILL MITCCHELL 教授的一篇文章，觉得和讨论有关，就转述了一段，原连接如下 http://bilbo.economicoutlook.net/blog/?p=36218#more-36218
