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.
IMHO this could be larger than most people would think. This made it affordable to export labor overseas, starting the power imbalance between employers and employees.
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.
