When I first read this I did think WTF?
Having read the thread I do see how this might work as a job creation measure - basically encouraging people to spend more on local domestic services out of untaxed income rather than more on imported goods out of taxed income. I guess it's the kind of tax break you can give people where you can guarantee it will be spent in the local economy.... It's a bit similar to thinking behind local currency schemes (LETS) which come out of the left/knit-your-own lentils rather than the right/upstairs downstairs side of the political spectrum.
But it's not much of a vision of a balanced economy though is it? A few % of people earning massive salaries in financial services, no manufacturing to speak of, massive rationing of the public sector and the rest getting trickle down benefits in the mcjobs and domestic service sector?
On the other hand the vision from the left seems to be the same thing but with a bigger public sector and more generous benefits for those who have lost out from the death of british manufacturing. As we have seen, that vision didn't turn out too well either.
Is it pie-in-the-sky to think we might build an internationally competitive sector that makes something other than financial products? Or is the future of mass employment really cutting each other's hair, cleaning each other's houses and digging each other's gardens?
