The more electric vehicles made, the more jobs that will be lost especially with new plants. Even taken with a huge grain of salt, the number of man hours reduced for electric vehicles is huge. Admittedly a bare bones Model 3 also has fewer parts due to its cost cutting design and lack of interior.
From NBC:
Hybrid cars combine electric drive hardware with a conventional, internal combustion engine, and require more labor — about 9.2 man hours compared with 6.2 hours for a typical gas vehicle. But an all-electric vehicle cuts that down to 3.7 hours, Mark Wakefield, head of the automotive practice at consultancy AlixPartners, told NBC News.
Fewer man hours to build a car=fewer employees, or the same number of employees working fewer hours.
