Are you sure about that? For recipients, there is potential to slack off while still receiving pay. Possibly to the point of doing other work (under the table? for their own household?). While this can be construed as still comparing favorably to BI ("at least we're getting some work out of some of them") it is not at all the same as there being no opportunity for fraud.

Meanwhile, there is tremendous potential for abuse and fraud by those giving out the basic jobs. A long running program whose criteria for success is "employ a lot of people at marginally useful things" is a large pile of money just waiting to be spent on making improvements that especially benefit the connected few.
