Maybe.They have a plan which means giving visas out that in turn will peg back wage rises in the red wall seats they won at the last election. Suicidal doesn't describe it.
It's as though they want to lose the next election.
The plan seems to be:
. take action that 'forces' the BoE to raise interest rates - they could simply instruct the BoE to raise rates but that would give the game away
. let the £ fall until the necessary interest rate has been reached (probably around 5% seems to be the level they think will kill off enough 'zombie companies and free up their resources
. the tax cuts etc. encourage 'sound' companies to invest by buying the resources freed up above
Edit: it's known as 'Creative Destruction'.
People are the most vital resource any nation has so , if we haven't got enough here already, what else can they do but import some?
