You are part of an emerging economy, rapidly growing wealthier and becoming a world power. To go with your new found status you buy a car financed with a loan from one of the Big Four Chinese banks. And it turns out that one in every two of you can't afford the repayments. In other countries big banks with default rates higher than 50% on their auto loans would be at the very least intensively audited by the authorities. In China they get ready to float them on the stock exchange.
