Take the case of public education alone. The principal difficulty faced by the schools has been the tremendous increase in the number of pupils. This has been caused by the advance of the legal age for going into industry and the impossibility of finding a job even when the legal age has been reached. In view of the technological improvements in the last few years, business will require in the future proportionately fewer workers than ever before. The result will be still further raising of the legal age for going into employment, and still further difficulty in finding employment when that age has been attained. If we cannot put our children to work, we must put them in school. We may also be quite confident that the present trend toward a shorter day and a shorter week will be maintained. We have developed and shall continue to have a new leisure class. Already the public agencies for adult education are swamped by the tide that has swept over them since the depression began. They will be little better off when it is over. Their support must come from the taxpayer. It is surely too much to hope that these increases in the cost of public education can be borne by the local communities. They cannot care for the present restricted and inadequate system. The local communities have failed in their efforts to cope with unemployment. They cannot expect to cope with public education on the scale on which we must attempt it. The answer to the problem of unemployment has been Federal relief. The answer to the problem of public education may have to be much the same, and properly so. If there is one thing in which the citizens of all parts of the country have an interest, it is in the decent education of the citizens of all parts of the country. Our income tax now goes in part to keep our neighbors alive. It may have to go in part as well to make our neighbors intelligent. We are now attempting to preserve the present generation through Federal relief of the destitute (贫民). Only a people determined to ruin the next generation will refuse such Federal funds as public education may require.

In the world of entertainment, TV talk shows have undoubtedly flooded every inch of space on daytime television. And anyone who watches them regularly knows that each one varies in style and format. But no two shows are more profoundly opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey shows. Jerry Springer could easily be considered the king of "trash talk (废话)". The topics on his show are as shocking as shocking can be. For example, the show takes the ever-common talk show themes of love, sex, cheating, guilt, hate, conflict and morality to a different level. Clearly, the Jerry Springer show is a display and exploitation of society"s moral catastrophes (灾难)， yet people are willing to eat up the intriguing predicaments (困境) of other people"s lives. Like Jerry Springer, Oprah Winfrey takes TV talk show to its extreme, but Oprah goes in the opposite direction. The show focuses on the improvement of society and an individual"s quality of life. Topics range from teaching your children responsibility, managing your work week, to getting to know your neighbors. Compared to Oprah, the Jerry Springer show looks like poisonous waste being dumped on society. Jerry ends every show with a "final word". He makes a small speech that sums up the entire moral of the show. Hopefully, this is the part where most people will learn something very valuable. Clean as it is, the Oprah show is not for everyone. The show"s main target audience are middle-class Americans. Most of these people have the time, money, and stability to deal with life"s tougher problems. Jerry Springer, on the other hand, has more of an association with the young adults of society. These are 18 to 21-year-olds whose main troubles in life involve love, relationship, sex, money and peers. They are the ones who see some value and lessons to be learned underneath the show"s exploitation. While the two shows are as different as night and day, both have ruled the talk show circuit for many years now. Each one caters to a different audience while both have a strong following from large groups of fans. Ironically, both could also be considered pioneers in the talk show world. (388 words) We can learn from the passage that the two talk shows______.
