The banks had been piling money into the system for decades into the run up, from memory in the UK it was something like around 250b per year. The bailouts themselves weren't actually that big of a deal. They also (mostly) paid or will pay it back afterwards.
In the UK the current state pension cost is around 100b and is projected to rise to almost 500b 50 years from now, whilst GDP will only double.
@TwoSheds it doesnt matter what is promised. I realise it's unfortunate but we literally cannot afford that.
