Re: Best solution ...
Either its enough to live on ( and enough for the disabled to live on, and those who can't afford a home to pay their rent with ), or it's pointless.
If it's going to be big enough for that, then it's unaffordable.
The tax allowance isn't a handout. It's progressive taxation. By that logic, the 80% tax the state doesn't collect after £12.5k is a handout too. It's not.
I'm not arguing that everybody would sit around doing nothing voluntarily. But I am arguing that a system that would be worth implementing would be so unaffordable that it would be impossible to implement.
