After living in both China and Canada for extended period of time, I've always wondered why China's society has such low trust compared to Canada's, and came up with a few possible contributing factors. One of them, I believe, is the lack of history-tracking entities like credit bureaus, meaning that people who abuse trust are not remembered. Lack of a proper justice system is another major contributor, meaning that people who abused trust can get away more easily. Take a few concrete examples, when buying a used car in Canada, you can check vehicle history, which will bring up any major damages to the car (except in some exceptionally elaborate scandal cases); when renting to a tenant, you check his/her credit history; after a car accident, you only have to exchange insurance information; if you ate something bad in a restaurant or a food truck, you report it to the health services and they'll get inspected, potentially closing it down costing the owner dearly. In China, those things are either non-existent or not very well run, making private commerce a risky venture, heck, even eating out is a risky adventure.
