Thatcher was responsible for privatisation, largely as a means by which to break the power of the unions. Blair outsourced government - because the elite assumed we had in turn outsourced that to the EU in perpetuity.
now our politicians are having to re-learn how to do their jobs and actually govern the country, not be figureheads to quangos and civil servants. This is why Starmer, lack of charisma aside, cannot effect change. He has no levers of power post Blair.
