As a result, a market economy encourages specialization: We become very good in a narrow set of skills or products, and exchange them for millions of other things we have no clue how to do or make. As a consequence, we end up doing remarkably few things and buying everything else from others.
这样一来，市场经济鼓励专业化：我们熟练掌握狭窄范围内的某种技能或产品，并以此来换取数以百万计我们不知道怎么制作的其他物品。因此，我们最终能做的事情少之又少，除此之外的其他东西都从别人那里进口。
