The same, the precise same arguments were made in 2009/10/11, and we got a decade of stagnant wages and now we are here, on the brink of a sterling deficit crisis, and a cost of living crisis. Both of which would be less acute if GDP were higher and people had more money to weather the storm.
Treasury orthodoxy has put the UK in a parlous state. Not borrowing to invest whilst rates were at rock bottom, and then index linking Gilts putting us on the hook for eye watering debt interest repayments, were the worst possible choices that could have been made.
The Treasury made these choices, against much advice, which have stifled growth, along with successive Tory governments.
And now, its more of the same. "We cant invest", despite the lack of investment putting us in this mess. But hey, if you (not you specifically JH) want to keep digging, be my guest.
If your final sentence proves to be right, its only a matter of time before the UK (if it is still a UK by then) drops out of the G7 and living standards fall below everyone's expectations of what it means to live in 21st century Britain.
Investment is beyond crucial. The economy desperately needs it. I only hope that this will become the prevailing narrative before its too late.
