On the member's last point, he wants the cost to fall primarily on those who change their behaviour, but there is no way to distinguish them. If we toughen up the UI rules there is no way to distinguish between persons who take a longer time to look for a job than others would and persons who legitimately cannot find a job because all the factories in their towns have closed.
There is no way; the system is not that specific that we can say some persons are not looking hard enough for a job so we are going to toughen up on them.
