Exactly. Let go of the mantra. A downgrade is not the end of the world. There's absolutely no risk of a default. Bond rates are low and borrowing is cheap. Quit Brexit, invest in infrastructure, invest in people, grow the economy, tackle tax evasion, compete in the world, and debt will shrink.
This is somewhat circular. By not reducing debt growth a downgrade would of happened sooner. Again you could be right more debt to a problem caused by inefficient use of debt is the answer.
Competitive economies are not competitive economies, austerity is not austerity, options are not options.
I make suggestions and try to cite some evidence to back up these. Perhaps you could counter the argument as it looks like you are not able to. Suggesting Brown's economic policy stopped having an influence on the day he left office was your last counter argument. Anything else?
