I am really saddened by this debate and the fact that the (so-called) Labour government is bringing the US style welfare to work policy over here.
First I think that some proportion of our society will always be less able to work for a living. Having been set up for failure by a crappy upbringing, low expectations, abuse, phobias, depression, social deprivation etc. etc. etc. Not always in a visible to their neighbours way, some people are lazy buggers (I am lazy I managed to avoid paid employment till I was 22 - then I got a very hard shop job working upwards of 50 hours a week - a big shock for a Humanities graduate with no experience).
Those who are 'working the system' will find a way to work the the new system to their advantage as that is their 'job'.
Those who are vulnerable and scared of being put into work situations they cannot handle will be left much worse off.
Some individuals may well benefit from being given work to do but it will benefit the employers more who will be paid to take on staff - therefore jobs will not be created.
There is too much 'I am working so they [feckless families on benefits]should be working' attitude being displayed - I feel guilty for not working despite not currently needing too thanks to tax payers (DH is a civil servant).
If we want a healthy working society then forced employment is not in my opinion the answer - it is a way for the Govt to appear 'tough' on unemployment and PR is not a good justification for any policy.
