The fears about getting a “Monday car” or a “Friday car” are valid about UAW-made vehicles (that they won’t be up to par): while unions accomplished a lot for American workers decades ago, those labor reforms have been codified in law - now they are just a racket that protects mediocrity (and in the case of public employees, strangles taxpayers & businesses).
Toyota makes great cars as well; more and more of them are made here (without unions).
I’ve toured Nissan and Toyota plants in TN and IN and the non-union workers appeared to be very happy and glad we were visiting. You can’t make line workers fake that.
