     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 (个人) . 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). One further solution is that the
government or social organizations set up some working places especially for the elderly where they are
independent.
     To sum up, all these measures have advantages and disadvantages. Therefore, it is reasonable to
expect that some combination of these measures may be needed to provide the care we hope to give to
our elderly generations.
