3.5B sounds like a lot, but Ford has around 175k US employees, if you divide that 3.5B over the ten years over the 175k employees, that’s only an extra $2000/employee/yr. $2000/yr is not going to help a factory worker’s future medical debt nor allow someone to afford a house or a family that couldn’t $2k ago.
Show me someone who wouldn’t take an additional 2K/year for the same work.
