But Japan would close the 30% gap (adjusted for purchasing power parity) between its per capita GDP and that of the US. The prevailing belief was that, by 2015 or so, Japan’s per capita GDP would more likely than not be 10% higher than in the US (in PPP terms).
日本的人口只有美国的三分之一，不可能成为世界首屈一指的经济超级大国。但日本能够弥补其与美国接近30%的人均GDP差距（以购买力平价衡量）。当时的普遍观点是，到2015年左右，日本的人均GDP很有可能将比美国高出10%（以购买力平价衡量）。
