英语翻译
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.(77) 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.(78) 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.

许多私立高等教育机构在全国各地有危险.不是所有将被保存,也许并不是所有的都值得去挽救.是低质量的学校就像是低质量的企业.我们没有义务去救他们仅仅是因为他们的存在.但许多欣欣向荣的机构,应该继续受到威胁.他们的工作做得很好的教育,但他们陷入财政困难,没有办法降低成本上升或（收入）显着增加收入.提高收费不会带来更多收入,每次费用涨,招生（注册人数）下,或金额,必须是在学生援助上.（77）学校是糟糕的产业,无论是公立还是私立.由于管理不善,但通常不会因为业务的性质.他们亏钱对每一个客户,他们可以从破产或者学生太少或太多的学生.即使是一个很好的大学是一个非常糟糕的业务.
它是高校,繁荣但威胁,我担心.低入学率不是主要问题.即使有充分的人数,他们会下.努力拯救他们,最好让他们私人的,是一个国家的必要性.（78）是没有根据认为私立学校就一定好于公立学校.有丰富的例子是相反的.任何人都可以叫国家院校排名最好的国家和世界.现在是不可避免的,公共机构将主导,并因此多样性是一个全国性的必要性.多样性的方式支持学校往往会给我们一个健康的多样性的教育形式.在一个不完美的社会,象我们这样的,统一的教育在全国各地可能是危险的.在一个不完美的社会中,多样性是一个积极的好.热心的支持者的公立高等教育知道必须保持民办高等教育健康.
