The administrative costs of the new rule could total $18.9 billion the first year – over 15 times greater than the $1.2 billion of increased wages that the administration estimates will be received by workers. In subsequent years, the ongoing management supervision costs imposed by the rule could total around $3.4 billion each year, almost three times the $1.2 billion of wage gains generated.
