.....due to expiration of benefits.....
That statement is a rings untrue to me. I thought benefits had been extended and re-extended more or less to perpetuity.
To go off the rolls means the person must have been out of a job for what? 24 months?
I take your point, but that's a problem of a different sort. A number of people, some tens of thousands, are losing their benefits during the Easter Recess. Those people are no longer counted as part of the workforce (maybe they never were, but we're debating government policy using government numbers).
