It's a fools argument to suggest that unions would somehow help/improve Tesla in any way, shape, or form...

You are only speculating that it is the union. It is a fact that Tesla cars are not well built. I have had more issues with my model S in 3 months of ownership then I have had in 20 years owning Japanese cars. The fact that EVERY major youtube Tesla owner has had a video of them hauling off their car in a flatbed speaks volumes of how poorly built Tesla cars are.
