Because launching space vehicles is about to bee very much cheaper, the number of satellites is likely to go up greatly. There?s lots of space up there so we could have millions of them. And if you have millions of loworbit satellites you can establish a global munications work that pletely does away with towers and poles. Speech is so flexible that I expect voice munication to bee almost free eventually： you?ll pay just a monthly fixed charge and be able to make as many calls as you want.

Not all will be saved, and perhaps not all deserve to be saved. There are lowquality schools just as there are lowquality business. 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 squeeze, with no way to reduce rising costs or increase revenues significantly. Raising tuition doesn?t bring in more revenue, for each time tuition goes up, the enrollment goes down, or the amount that must be given away in student aid goes up. Schools are bad businesses, whether public or private, not usually because of mismanagement but because of the nature of the enterprise. 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, 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. There is no basis for arguing that private schools are inherently(固有地 ) better than public schools. Examples to the contrary abound. 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 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.
