There is more money long term by investment in infrastructure, projects, education, etc., which is exactly why it is beneficial to run a a small deficit because you reap many rewards in the future, which is exactly why most countries purposely run a deficit. It is like buying a house, that puts i in a huge amount of debt and your debt to income ratio goes extreme, but you get the long term benefits of a mortgage free house in the future, the house value appreciating, and all the other benefits of house ownership.
Long term the debt will have an increasingly lower value thanks to inflation.
The dept to GDP ratio has remained the same so the growth has kept in line with exactly the amount spent, so you are wrong.
"there" [sic] spending can easily be defended as their deficit ratio was well within recommended limits and matches the UK's historic average, the same as the average of con governments.
