Well that's the banks and, well they'll blame the consumer's demand for debt.
The banks wouldn't issue debt if there wasn't someone living beyond their means. In America, it's something like $103 000 per person of national debt (not personal). But if you look at the USA development, you can see why it happens.
China? Evergrande a prime example.
Central banks keep the banks in check using interest rates.
The banks issue loans or mortgages to chumps who then blame government when they loose their jobs and can't pay back the debt.
So whose to blame? My finger points to the guy with a five bedroom home, two cars and a boat, a second home etc. all taken out and paid monthly.
