If you read the link, you'd learn that in the 10 most populous US states, 2.4 million minimum wage workers are victims of wage theft annually. This loss averages $3,300 per (full time, year round) worker per year, and just under $8 billion in total per year.
And that's only minimum wage workers, in a subset of the US.
Was there a particular reason you were under the impression that wage theft was uncommon?
