I'd add that in 1970, the intermodal shipping container became an ISO standard. Containerization has been developing since 1956, and along with minicomputers, would have an impact on world trade and manufacturing for decades to come.
I'll bet if you look this is the start of die off of Unions. Now there is an alternative to employees who start demanding living wages and benefits, you can build your factory in another country where labor has few rights. The only unions you would expect to survive are ones where the labor can't be outsourced. Service unions. Transportation. Mining in cases where the material is too expensive to ship like coal.
Amazon is interesting too. They brought the global supply chain to the consumer. What consequences will that have?
Though Teachers Unions would a counter example.
