Get high school diploma, at least. Without that, you are occupationally dead, unless your name happens to be George Bernard Shaw or Thomas Alva Edison and you can successfully drop out in grade school.
Get a college degree, if possible. With a B.A., you are on the launching pad(发射台). But now you have to start to put on the brakes. If you go for a master's degree, make sure it is a M.B.A., and only from a first-rate university. Beyond this, the famous law of diminishing returns begins to take effect.
Do you know, for instance, that long-haul truck drivers earn more a year than full professors？ Yes, the average 1977 salary for those truckers was $24,000, while the full professors managed to average just $23,930.
A Ph.D is the highest degree you can get, but except in a few specialized fields such as physics or chemistry, where the degree can quickly be turned to industrial or commercial purposes, you are facing a dim future. There are more Ph.Ds unemployed or underemployed in this country than in any other part of the world by far.
If you become a doctor of philosophy in English or history or anthropology or political science or language or—worst of all—in philosophy, you run the risk of becoming overeducated for our national demands. Not for our needs, mind you, but for our demands.
Thousands of Ph.Ds are selling shoes, driving cabs, waiting on tables and filling out fruitless applications month after month. And then maybe taking a job in some high school or backwater college that pays much less than the janitor(看门人) earns.
You can equate the level of income with the level of education only so far. Far enough, that is, to make you useful to the gross national product, but not so far that nobody can turn much of a profit on you.
According to the writer, what the society expects of education is to turn out people who ______.
A．will not be a shame to the society
B．will become loyal citizens
C．can take care of themselves
D．can meet the demands as a source of manpower
A.张某应单独赔偿何某的损失
B.张某、刘某应平均分担共同赔偿何某的损失
C.张某应与刘某的父母共同分担何某的损失，但张某应负主要责任
D.应由张某、刘某的父母与何某共同分担何某的损失
