During the last 14 years there have been numerous examples of reckless spending with public money which the Tories are still doing now!
I am half inclined to agree with this, but, with public services falling apart for deliberate lack of government spending on them I'm more inclined to say that government spending has been woefully misdirected in the interest of government 'small state' ideology, 'austerity', and, as made clear by the pandemic spending, blatant cronyism and corruption.
Rather than focussing on the 'debt' itself I think we should be asking why government has increased the debt with little tangible benefit to the UK. and judging it accordingly.
The country is more than broke
As usual, I would point out that aa government which has the power to issue its own sovereign currency cannot become 'broke' because it is highly unlikely to renege on its 'debt'.
Common sense' prompts me to ask why people and institutions are keen to hold 'government debt', in the form of bonds and government savings vehicles?
The answer being that they know it is the safest form of saving for a guaranteed return in the form of interest payments and with the knowledge that their principle will be repaid to them any time they ask for it back. The holders of government 'debt' don't aren't very kindly lending their money to the government, they view it as a very safe way of saving. Some even see it as a good opportunity to speculate through the secondary bond market...
Do people not understand economics?
Well, if they see a national economy as being the same as a household or company economy they clearly don't understand economics...
