A really good pair of leather boots, the sort that would last years and years, cost fifty dollars. This was beyond his pocket and the most he, Vimes, could hope for was an affordable pair of boots costing ten dollars, which might with luck last a year or so before he, Vimes, would need to resort to makeshift cardboard insoles so as to prolong the moment of shelling out another ten dollars.
Therefore over a period of ten years, he, Vimes, might have paid out a hundred dollars on boots, twice as much as the man who could afford fifty dollars up front ten years before. And he would still have wet feet.

So I admit that that the argument over he proposal to devolve a limited income tax-varying system on a par with Scotland - dubbed the “lockstep” -
Since I believe that Scotland has not used these powers it seems likely that the Assembly will be unlikely to do so as well.
So we seem to be offered a referendum that offers a choice of a Tax system that may not be (or even unlikely) to use.
So what's the point?
As i said I may like most of the Welsh Electorate find the nitty gritty of economic argument difficult to grasp . But this looks like sheer tokenism . I'd vote yes in referendum for this because its a small step but in doing so I will not be expecting it to change Wales and how we raise our own money much.
