thats an overly simplistic way to look at it. Of course you can never get more money from your employees' purchases than you give them, that makes no sense. The point is using your market power as a large employer to raise market salaries. People will not want to work for your competitors or other sectors if they pay half what you do. So when you rise, naturally other salaries will rise too. And those other workers will also be buying cars.

Whether that makes sense economically is a difficult problem to quantify, especially over any fixed timeframe. I would guess not, at least if your brand isnt insanely strong (on the level of half or more people with enough money would buy it)
