And we've been living off it these last twenty years.
When Labour brought in tax credits it was "to make work pay for hard-working families". But actually all it meant was that employers could pay less in wages while there was still plenty of money swilling around to put towards buying things. No matter that this is money not generated by any activity other than collecting tax and giving it out to folks every year: it's there and you can spend it. Then things semi collapsed in 2008 so the Tories' answer was just to print more. As well as keeping on recycling tax take to prop up poor earnings.
So we've all been living off the magic money tree a long time. Not just the people claiming the £38bn of in work benefits every year, but also everyone who sells anything to them ie every person involved in economic activity.
Looks like it's set to stop now, maybe, but it's been a magic money tree. Hasn't it?
