Poor countries don't want to expand domestic demand. More than 20 years ago, China tried to expand domestic demand. To expand consumption, it is necessary to give workers more wages, which will increase the cost and raise the price of products, that is, the price will rise, thus forming a snap purchase and causing social unrest.

Therefore, at present, China can only adopt the mode of expanding exports, creating domestic employment opportunities, and gradually cultivating people's spending power, and then gradually reducing exports and adopting the mode of focusing on domestic demand.
