It's not a question of 'free money', I struggle to understand why you feel the need to simplify such an incredibly convoluted matter such as the economy.
The idea would be to make use of the incredibly low interest rates of which our country can borrow at, as to invest in a re-industrialisation strategy and lift millions of people out of a future of debt and struggle.
As for the repayments, anyone with sense would understand that with a sustainable and sensible rate of inflation, the interest would be wiped out altogether.
The way we have been doing things obviously isn't working. It's time for something new.
Okay, I'd like to challenge this if I may. Yes, interest rates are very low, but even with interest rates that low, we are paying back roughly 3% of GDP per year in interest payments. In the last 30 years, UK GDP has exceeded 3% just 4 times.
Now call me old fashioned if you like, but borrowing makes sense when your income rises by more than the cost of borrowing. When it doesn't, it's economic hara-kari.
