I'm pretty sure they're starting to actually implement a system where after x amount of time of you not getting a job whilst on JSA you have to work in a large supermarket on unpaid work experience, to continue to get your JSA.
Whilst I personally think it's an incredible idea to get the lazy benefit claimers off their behinds, it could arguably be seen as some form of Slavery, as one could argue it is forced labour, and also not far from what the OP suggested.
I guess if we look at Stalin's rule of Russia as well. The industrial boom, was basically forced labour/slavery as well. Whilst in no way do I think that the atrocities he committed were humane or justified, you cannot deny the sheer amount of productivity that was created out of it. Stalin managed to effectively have the entire British Industrial Revolution, in 10 years for Russia due to what he did with labour. Is it morally and ethically correct. Absolutely not. Was it incredibly productive. Yes.
I guess I should also point out that slavery happens all over the world still - including in Britain, there are often documentaries or even just your 'customs control' tv program, that frequently show conditions where people are basically working in slave labour conditions.
Slavery itself has far too many moral and social hazards. For one you shouldn't ever have ownership over another person - God knows how many people would abuse their slaves, and history teaches us that whilst some slaves were treated well, others were treated horrifically, as they basically had no access to the justice system, so people could get away with it.... What's more as they were the 'lowest' of society, people didn't really care that they were treated so harshly....
I'm not going to deny that it's not effective. Because it can be. However, the human rights infringements, and the issues created morally surrounding this are atrocious.

Stalinism was incredibly inefficient on the whole, I can't believe you brought it up as an example. The Holodomor was largely an effect of Stalin's approach to communist reforms.
