For generations, many people in the UK (known as the very rich) have 'made their living' by simply inheriting land (originally from a distant relative who got it from a monarch who took it from someone else simply by force) and letting people use it in return for rent. Nice work if you can get it...
I tend towards 'all property is theft' (which raised the question is theft always wrong, can't it sometimes be justified - I'll leave that open for another time).
In my view, if being a citizen of a country means anything it means an equal share/right to the resources of that country - its 'our' country, we are all born equal as citizens, so what argument against this can there be?
A share of the resources of the UK is enough to give every citizen the means (with their own labour) to support themselves - in my view that is the states duty discharged, you can offer a citizen a means of support but you can't make them use it.
Workfair - expecting people to work to support themselves, and giving them a safety net opportunity to do so is not a million miles from what I set out above.
Immigration - this is an issue because there is a distinct link between the land/country and its citizens - it is for other countries and citizens to decide how they run their affairs, but how the UK is run should be solely down to the citizens of the country - nothing is owed to, or asked of non-citizens.
EU - well the Euro debacle shows that the EU is simply too big an area to seed new ways of working/thinking - you don't start a fire with large logs, you start with a spark, tinder and twigs.
Where 'workfair' gets a bit of a bad name is that people say it 'forces people to work' which is slavery. But it doesn't... people are entitled to not-work and freeze/starve if they prefer... Whether the amount of work required and the level of reward returned are equitable is a different issue, which does need attention, but that is a detail, not an flaw in the principle. If people don't want to use the state workfair programme, and still don't want to freeze/starve they should (of course) have the opportunity to do so working for themselves or for others on the private sector.
The choice is yours/theirs - chose to support yourself or not - what you can't choose is to make others support you (and that should apply to landholders as much as bog-standard citizens).
