Japan used to provide good quality service at a cheap price. That's why our salaries don't go up.
In other countries, companies provide good quality service at an expensive price. That's why people's salaries are high.
Because Japan provides things at a relatively cheap price, Japanese real estate and companies are being bought off by foreign companies.
