GDP includes all production, not just wages – It accounts for corporate profits, government spending, and investments, which individuals may not directly receive as income.
但是这里说的几个部分:corporate profits 不也是职工的工资吗?government spending 不是公务员的工资吗?investments 难道不会变成生产者的工资吗(比如 invest in machines,那么这些机器的生产者不就得到了这部分工资吗?)
