罗切斯特的经济学教授Steven E. Landsburg写道：如果你不能改变一个人的消费，你就不可能对这个人收税，即便你把他银行里的钱都拿走也不行。郭凯：steven不过是说税收负担最终未必落在那个交税的人头上。我想起这大概就是所谓的"富人税（奢侈品税啊，房屋买卖课税啊~~~list~）"为什么总是伤害穷人的理论。
In this stupid country, we have enough physician, sufficient pharmacuticals and devices, but we don't have ownership, so the health system is a mess. It is growing, but it can not be evolving, re-organizing, or even moving. The system is learning, yet without development. All of these resulted from the idea that no one knows who owns it. 租值消散（dissipation of rent）或租值耗散理论(The Theory of Rent Dissipation)在国内译作"租值耗散"，又称"租耗"。 -- 公地的悲剧，产权的经济学。

[zt] Aid.vs.Trade
美欧的aid不能转变非洲社会，但是中非的贸易trade却能塑造shape一个新的非洲。en ~~ maybe a new idea
But aid from the outside cannot transform whole societies, whole countries. That can only come about through producing things and trading them or doing something someone else wants to pay for. Ironically, it is the capitalist West that still sees Africa as a continent that needs aid, while Communist and former Socialist governments like China and India see it as a business opportunity.
