Such a massive diversion of resources “away from goods and services directly useful this year,” I argued, “is a good bargain only if it boosts overall annual economic growth by 0.3% – or 6% per 25-year generation.” In other words, it is a good bargain only if it collectively has a substantial amount of what financiers call “alpha.”
资源“从有直接用途的当年商品和服务上”如此大规模的“转移”，我指出，“只有在它能提振年度总体经济增长0.3%以上，或在25年时间里提振6%，它才是划算的买卖。”换句话说，只有在它整体而言具有相当大的金融业者所谓的“阿尔法”时，这才是一笔划算的买卖。
