[完成句子]The same year Henry Ford shocked the world with the $5 — a-day minimum wage scheme， the greatest contribution he had ever made. The average wage in the auto industry then was $2. 34 for a 9-hour shift. Ford not only doubled that， he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn‘t involve all awful lot of training or education. The Wall Street Journal called the plan “an economic crime”， and critics everywhere laughed at Ford. But as the wage increased later to daily $10， it proved a criticalponent of Ford’s dream to make the automobile accessible（可及的）to all. The critics were too stupid to understand that because Ford had lowered his costs per car， the higher wages didn‘t matter——except for making it possible for more people to buy Cars.

A、criticized by the media
B、the low wage in the auto industry
