Dinahmo Are you doing the same now with UC? Especially in the context of self-employment. About one in six workers is now self-employed and they're locked out of Universal Credit unless they earn the equivalent of minimum wage x 30 (hours), including those over 60, which is a change this government has brought in. This means that every time the minimum wage goes up, people receive less. In other words, increasing the minimum wage ( much lauded government initiative) doesn't actually benefit the low paid and in the case of the self-employed makes them worse off.
The amount which is "clawed back" from earnings also means that, in practice, nobody in work without children even gets anything from Universal Credit.
It's all smoke and mirrors. WFTC, for all its flaws, was better for the low paid than Universal Credit. I've done the sums. Its abolition has been a contributory factor to the rise in family/child poverty and why the majority of people now suffering poverty have at least one member of the family in work.
Not only is the implementation of UC bad, but there all sorts of loopholes which employers can use to escape paying the living wage. The Conservatives and their supporters won't tell you that!
