Many private institutions of higher education around the country are in danger.Not all will be saved,and perhaps not all deserve to be saved.There are low-quality schools just as there are low-quality businesses.We have no obligation to save them simply because they exist.But many thriving institutions that deserve to continue are threatened.They are doing a fine job educationally,but they are caught in a financial difficulty,with no way to reduce rising costs or increase revenues (收入) significantly.Raising fees doesn't bring in more revenue,for each time fees go up,the enrollment (注册人数) goes down,or the amount that must be given away in student aid goes up.(78) Schools are bad businesses,whether public or private.not usually because of bad management but because of the nature of the business.They lose money on every customer,and they can go bankrupt either from too few students or too many students.Even a very good college is a very bad business.
　　It is such colleges,thriving but threatened,that I worry about.Low enrollment is not their chief problem.Even with full enrollments,they may go under.Efforts to save them,and preferably to keep them private,are a national necessity.(79) There is no basis for arguing that private schools are bound to be better than public schools.There are plentiful examples to the contrary.Anyone can name state universities and colleges that rank as the finest in the nation and the world.It is now inevitable that public institutions will be dominant,and therefore diversity (多样性) is a national necessity.Diversity in the way we support schools tends to give us a healthy diversity in the forms of education.In an imperfect society such as ours,uniformity of education throughout the nation could be dangerous.In an imperfect society,diversity is a positive good.Eager supporters of public higher education know the importance of keeping private higher education healthy.

在这个国家里,许多私人创办的高等教育机构面临困境.但并不是所有这些机构都能被挽救,或者说值得挽救.就像有劣等企业一样,低质量的学校也是存在的.不能仅仅因为它们存在,我们就得去保护它们.但也有很多值得发展的优秀机构受到威胁.它们在教育方面做得很好,但却因为找不到减少日益增长的开支和增加收入的有效方法而面临着经济危机.学费的上涨并没有带来更多的收入,因为每次增加学费,注册人数就下降,否则给学生的经济援助总数就上升.学校不是好企业,不论公办的还是私人创办的.通常不是因为管理无方而是由于企业的本性使然,学校赔钱给每个消费者,学生太多或太少都能导致学校破产,甚至一个非常好的学校也是一个失败的企业.
我所担心的就是这些繁荣却受到威胁的大学.低注册人数不是它们的主要问题,即使注册人数充足,这些学校也可能走下坡路.尽力去挽救它们,更好地保持它们的私有性,是国家的必然.并没有根据说私人学校一定比公办学校更好,有许多例子却证明恰恰相反.任何人说出在国家或世界上有名的公办大学.现在公办机构占优势是不可避免的,因此多样性也是国家发展的必然.
在我们所处的这个不完美的社会里,整个国家用统一的教育方式是很危险的.在一个不完美的社会里,多样性是一种正面的好.热切的公办高等教育支持者知道保持私人创办的高等教育健康发展的重要性.
