middle class growth

Middle class growth refers to the expansion of the middle class—either in size, as more people enter middle-income brackets, or in prosperity, as existing middle-class households gain wealth and purchasing power.

The phrase appears frequently in economic policy discussions: The candidate promised policies that would stimulate middle class growth.

It often serves as a measure of economic health, with the assumption that a thriving middle class indicates broad-based prosperity rather than wealth concentrated at extremes.
