A serious problem for today’s society is who should be responsible for our elderly and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem.

First, employers should take the responsibility for their retired employees. To make this possible, a percentage of profits should be set aside for this purpose. But when a company must take life­long responsibility for its employees, it may suffer from a commercial disadvantage due to higher employee costs.

Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor.

In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions(养老金). Furthermore, some institutions should be created for senior citizens, which can help provide a comfortable life for them. Unfortunately, as the present situation in our country shows, this is not a truly viable answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young.

One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent.

To sum up, all these options have advantages and disadvantages. Therefore, it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations.

It was once common to regard Britain as a society with class distinction. Each class had unique characteristics. In recent years, many writers have begun to speak the ‘decline of class’ and ‘classless society’ in Britain. And in modern day consumer society everyone is considered to be middle class. 

But pronouncing the death of class is too early. A recent wide-ranging society of public opinion found 90 percent of people still placing themselves in particular class; 73 percent agreed that class was still a vital part of British society; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an important part of British society. Britain seems to have a love of stratification.

One unchanging aspect of a British person’s class position is accent. The words a person speaks tell her or his class. A study of British accents during 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice, Most people said this accent sounded ‘educated’ and ‘soft’. The accents placed at the bottom in this study, on the other hand, were regional city accents. These accents were seen as ‘common’ and ‘ugly’. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.

In recent years, however, young upper middle-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song ‘Common People’ puts forward the view that though a middle-class person may ‘want to live like common people’ they can never appreciate the reality of a working-class life.
