Remarkably few people are 'deliberately unemployed', but whatever.
That depend on how we define "deliberately unemployed", if we define it as someone, who will work very hard to stay on unemployment benefits, yes in that case it's relative few people, and honestly there are not a lot which can be done about these people, but in general you need to find ways to punish these people, so that the general population don't stop supporting the existence of help to unemployed people.
But there are a lot of people, who don't want to take jobs which are "beneath" them, others are not willing to learn the skills necessary to get even a basic job or even people whose selfworth are so destroyed that they are terrified to fail one more time. These people need to be pushed in different ways back into the work force.
