All governments will expand the role of government. Can you find me one that has ever decreased its scope in a meaningful and permanent way?
They will (ideologically) shrink certain aspects of the state by "outsourcing" or handing it over to private companies. e.g. If you think that the welfare and healthcare aspects of the UK state are currently "expanding the role of government" then you're misinformed. If you think that there hasn't been "austerity" for government services in the last few years, then you don't know the UK at all.
Banking will be likewise, they don't believe in meaningful financial regulation.
Let's just stop pretending one is better than the other so we can focus on what is important.
And in terms of this government where the PM, Mr Sunak, is an ex-Goldman Sachs guy, it is an extraordinary claim. Even absurd.
