Not Murphy's Law
Many of the policies JC is espousing have been validated by external sources. For instance Austerity has been soundly rubbished by most economists ( and the IMF, etc ) as having kept us in recession for longer and deeper than needed and is purely a political exercise to destroy the state, starve public services of cash, cause them to 'fail' so they can be privatised on the cheap...
Tax avoidance by the uber rich and business = the deficit and coupled with a Tobin Tax ( most of the EU are in favour ) would provide significant funds to invest rather than cut
A living wage, reduces the state burden and provides individuals with disposable income further helping the economy
And Public QE puts cash into the economy rather than Banks Balance Sheets ( where it will end up eventually anyway! )
