Here in CT the local NPR station interviewed a bunch of (again, local to CT) restaurant and business owners.

They all said the same thing:
People apply just to prove they are looking in order to get the unemployment and bonus. Some "applicants" come out and say that
People who are serious only want to work 1/2 time so they can get part-time unemployment and full bonus $$
The serious applicants aren't always qualified for the jobs that are open.

For example, the landscaping company needs someone experienced in design, drainage, etc....not a body to push a mower in straight lines.
