举例说明什么叫价格管制？当政治人物被说服制定法律，将产品价格维持在低位时，他们就创造了价格上限（price ceiling）：产品价格的最大值。美国的房租管制法（Rent-control Laws）是价格上限的一个例子，房租管制的政治理论在于栖身之处是一种需要（need）而非想要（want），而没有管制的住房均衡点会太高，让很多民众无法负担。

在没有成功之前，才华等于狗屎，只有成功才能证明你的一切，你不能坚持你就不配成功。

Every day is a new opportunity to change your life.

现在，我想趁这个给机会，给大家一些人生经验。漫漫人生路啊，你会发现并不总是公平的，你也会发现本不属于你的不可承受之重，却重重地压在你的身上，而且这些并非合理。但是，你必须低下头，并且抗争！抗争！抗争！永远永远不要放弃，一切终将变好。看看我是怎么被对待的，尤其是媒体对我的攻击。历史上没有一个政治家，我非常肯定地说，比我受到过更糟，更不公平的待遇。但是，你不能被他们打败，在你的人生的追梦路上，你不能被批评者和否定者绊住脚步。我想这就是为什么我赢了，谢谢，我想这就是为什么我们胜利了。逆境让你变得更加强大，不要屈服，不要退缩，不要停止做你认为正确的事情，一切值得做的事情。必定要经历诸多磨难，你所做的事情越正义，你受到的阻力就越大。我已经取得了巨大的成就，在很短的时间内成为了总统。

Now I want to take this opportunity to give you some advice. Over the course of your life, you will find that things are not always fair, you will find that things happen to you that you do not deserve, and that are not always warranted, but you have to put your head down, and FIGHT! FIGHT! FIGHT! Never ever ever give up, things will work out just fine. Look at the way I've been treated lately, especially by the media. No politician in history, and I say this is great surety, has been treated worse, more unfairly. You can't let them get you down, you can't let the critics, and the naysayers get in the way of your dream. I guess that's why I won, thank you. I guess that's why we won. Adversity makes you stronger, don't give in, don't back down, and never stop doing what you know is right. Nothing worth doing, ever ever ever came easy, and the more righteous you fight, the more opposition that you will face. I've accomplished a tremendous amount, in a very short time as president.
