Because to spend more would be to going back to having a current spending deficit, which is the road to national economic ruin. We need to run big budget surpluses for many years to pay off a big chumk of the national debt, otherwise the interest payments on the debt will continue to outrun the budgets of various government departments like education. We can't borrow to pay for day to day spending, when the next downturm inevitably comes it'll makebthe national economy hugely vulberable. Nor can we tax our way to prosperity.....the tax take as a % of GDP is at its highesy ever, and to try to tax the Amazons of this world will fruitlesslynsee such compabies flutter their registrations into other jurisdictions. I agree with you in principle Clint but in practice ongoing spebding restraint is the only realistic policy.
In a way the UK economy's predicament isn't too disimmilar to that of Wasps, or, technically, CCFC.
