     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 life-long

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

in-situations 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(选择) 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.
