Lincoln eliminated that. When unions kill car companies and set up the scenes for Japanese, Korean and European car companies to decimate USA car sales. The strikes forced a high degree of automation on US car makers = 75% of jobs gone over 40 years. Japanese, Korean and Eurpoean car makers delevloped huge RoRo car carriers (
https://en.wikipedia.org/wiki/Roll-on/roll-off). In 1960 cars were lloaded by cranes on slings and 10% had damage and each one took an hour os so to load/unload. The RoRo were built like parking lots. Drive the car down the long ramps on 7-10 levels, 5-10 cars wide. Park the car and go for the next car on foot while a rigger tightens chains to hooks on the car. Now you know what those hooks are for - RoRo loading. A ship could be loaded in a day, and unloaded as there were many drivers and ramps going at the same time.
Unions killed US car industry, it is true. They struggle on byautomating and eliminating jobs and fasteners etc. Often woder why things are not repaired any more? Automation in assembly eliminated screws = now welded or rivetted = no repairs possible. They hate Tesla and want the unions to ruin Tesla so they can force their lame electric cars on you. American electrics have failed because the car makers built in huge dealer work potential. Ever wonder why Tesla has no dealers? Electric cars do not need dealers. Do you have a toaster dealer? Take in your toaster every few months for service etc. The whole car industry will be wrong out like a chickens neck by electric cars as allmost all dealer work will be gone. No engine work - electric motors run 1 million miles. No mufflers at all, brakes last 5 times as long, tires can lasy 500,000 miles if made with urethane etc. on and on. Tesla is your greatest friend. Conventional Car makers are spending millions in bribes to kill Tesla via crooked politicians....(yes, I mean paper bags of cash - the political donations by cheques are small and are within the legal limits)
