I heard the same a few years ago - that PPI was acting as a massive stimulus to the economy. Just proves what I've always thought; that re-distributing wealth from the rich to the poor is beneficial to a nation's economy. The effectiveness of QE at doing what was intended; boosting GDP is still in question, however it certainly can't be said that it has led to massive inflation.
I would be interested in hearing more.
The QE would have been better giving every working household - top 3% - an equal share. I know every UK worker would have got £10,000+ it was on a debate somewhere time ago.
Give me ten grand and it would just sit somewhere as cash.
