When Henry Ford set minimum salaries, he wasn't impacting the wages of the engineers who designed the cars - he was impacting the wages of those who made less than $5 at the time the change was made. A minimum wage was being set, not an 'average' wage. So comparing a $5 minimum wage to the 'average wage today including white collar workers like line engineers' fails to be a convincing comparison. It's even less convincing now that I realize, after reviewing your comment, that you're including overtime wages for "Tier 2 union employees" when MrGilbert's data specifically doesn't include overtime wages. If you need to work overtime today to have the same relative affordability as that available a century ago - that's not progress!
Yes, yes - perhaps the autoworkers we are talking about are not 'average' and own fewer cars per household. And yes, yes - moving the minimum wage probably resulted in wage increases for higher paid workers as well. If you want to move the goalposts again do some legwork and show some work, otherwise you're just promoting a paper-thin narrative on the basis of "but what if".
And when it comes to 'automotive household income' the numbers work out even worse than MrGilbert's example. The average American household owner more than one car per driving adult. https://www.bts.gov/archive/publications/passenger_travel/ch...
