Gittens tries to defend the arrogance of titling his new book "Gittinomics" claiming he is a demigod overlord of the economy (phew! I'd hate to have misinterpreted renaming a science after yourself as arrogant). But then backs it up with:
Most of the things capitalism has to offer us are good - provided we don't overdo them. Trouble is, the system is usually pressing us to overdo them.As the overlord sees it- the problem with the capitalist system is that we don't behave how he would like us to. We anger the great Gittens with our selfish optimising.
