Surplus to requirements
> and it would be the basics, around the level of the pension, say £130 a week or so
But then what?
The thing about relative poverty - the thing that all the poverty charities love about it - is that can NEVER be fixed. Why is that "good"? Because it is their raison d'etre and will assure them recognition, moral superiority, political influence and some people a job forever.
But that 130 quid a week isn't just a sign of wealth, it's a sign of national surplus. It shows that we have broken out of the more money == more food == more surviving children cycle. However, there is a downside.
We know implicitly that you don't make everyone richer by doubling everyone's pay. So that suddenly many more people can afford that £90,000 Lexus LS. At that point demand will outstrip supply and all you will have done is stick a rocket up the bum of inflation and soon everyone will be back where they were (including the Lexus owners).
No, if you want to be able to spread the handouts around, the country has to produce more per unit of labour. That was what the industrial revolution with it's harnessing of power sources did for us. Before that the energy available to a worker was their muscle - or their horse's muscle power. After that it has trended towards the infinite.
But we've reached the limit of energy supply. Sure: we can produce more power, but there's a cost. The next step would be to increase efficiency of production: more widgets made per unit of labour. Apart from making us all wealthier, it'll also produce more Lexus's to satisfy the increased demand.
It would also raise the amount available for handouts by more than the rate of monetary inflation. So even those who don't / won't / can't work would still get a pretty nice set of wheels. Even if the roads got so jammed that you'd need a flying car, instead.
