Ah, it's not finding a job that's the problem, it's finding one that they think has the following features:

They have sufficient qualifications for it.
The employer is prepared to employ them.
The pay is sufficiently higher than welfare and having all that free time.

Basically unlikely to occur by choice. Industries suffer as there is no cheap labour as the rates that would be internationally competative are below welfare benefit.

For some to achieve there has to be the fear of where they are trying to escape from. If (as is so true in the UK for example) housing, money, schooling, healthcare are your rights even if you've never worked a day in your parasitical life then why bother trying? Even jails have fairly decent minimal standards (as opposed to Junior Doctor accommodation that has NO minimum standards).

Yes, some will suffer as they will in any system. But a leaner meaner system will benefit the majority to a greater degree. And I'd imagine even if having to work is a shock to the system, but ultimately leads to greater self respect.
