"But the economic model was built on everlasting growth - the odd fallow year was never factored in."
But spending wasn't sustainable in the good years either. In the fallow years the borrowing had to be even higher to keep things ticking over.
"Debt is grand if your economy grows year on year, you can pay the interest out of your economic growth."
Debt is never really grand, it's only "OK" if the repayments are under control and you can actually repay the capital too. You can't just rely on inflation to make the debt go away.
There's nothing really wrong in getting into manageable debt for certain things.
There's a huge problem in having to use credit just to fund your normal lifestyle, and that's what Governments have been doing pretty much every year since WW2.
The politicians could see this coming, but none of them wanted to tell the public that the spending either had to stop or taxes had to go up. They all just let the debt mount and our dependence on credit to fund our lifestyle increase.
"doing what comes naturally - profit seeking - in a free for all environment"
And that should be fine, that's not wrong. Leave them to it, but let them fail when it all goes wrong.
We made an economy where we became utterly reliant on the banks to both be the mainstay of our economic productivity and to also fund the Governent's normal day to day spending. And that's why they couldn't be allowed to fail.
