The US Private Sector Job Quality Index (JQI) is an indicator that assesses the labor market in the United States of America as a whole, based on one key characteristic – employee satisfaction with the wages they receive. And, since 1990, this indicator has been steadily going down.
The matter is not so much with a decrease in income, but with an increase in prices, especially for real estate, medical care, higher education, and utilities. As a result, despite the growth in wages, its purchasing power is steadily falling.
For example, if, over the past 20 years, the salary of Americans has grown by 14%, then the cost of a private house – by 101%.
