It is difficult to get a welfare client’s wheelchair repaired．Once my wheelchair needed repairing， and I notified my caseworker. She gave me a lecture that I hadn’t taken good care of my wheelchair.

Then she told me that I must have the patience to wait until she had the time to report my wheelchair

conditions to my medical worker. Then the medical worker called the wheelchair repair companies to get the cheapest bid and informed the main welfare office at the state capital．It took them another

several days to consider the matter. When they finally got my wheelchair repaired，I had been confined

to bed for more than half a month．

Compare the new welfare system with the old one and you would find a world of difference between

the two. Under the new welfare system, the law encourages welfare clients to work on their own for a

gradual shift away from welfare, and this is not the case in the past. Welfare clients now can develop

their talents to make money. In the past, they often cheated to bleed the system for a few extra dollars.

Now caseworkers will gladly help their clients find appropriate jobs rather than act like detectives to

try to seek out any unreported properties. Today many welfare clients have made a choice to live a life

of complete honesty and they tell the truth to caseworkers and declare any extra income they make.

In cases like this, caseworkers will feel greatly relieved because they don't need to search for any cheating as in the past.
