Of course, a situation where GNP increases while wealth declines can’t last forever. When an economy eats into its productive base in order to raise current production, eventually GNP will decline, too, unless policies were to so change that wealth begins to accumulate.
当然，GNP增长伴随着财富减少的情况不可能永远持续。当一个经济体为了提高现有生产力而开始消耗其生产力基础时，其GNP最终也会下降。除非它改变政策以开始积累财富。
