The British economy is now growing fast by current European standards, so 2% of GDP is becoming a larger sum. (The same is true of the UK’s similar commitment to the United Nations to spend 0.7% of its GDP on international development assistance.)
从经济方面反对将国家财富的固定百分比分配给特定的部门预算有着充分的理由。英国经济按照目前的欧盟标准正实现快速增长，因此GDP的2%意味着更大的金额。（英国像联合国承诺将其GDP的0.7%用于国际发展援助也是同样的状况。）
