Since 2000, the median US wage has risen about 1%, adjusted for inflation.

But over the same period, the median wage for:

• high school dropouts,
• high school graduates with no college education,
• people with some college education, and
• people with Bachelor’s or higher degrees

have all decreased. In other words, within every educational subgroup, the median wage is lower now than it was in 2000.
