Of course, the voluntary quotas were to protect the Big 3 from their Japanese competition. And now Toyota is one of the Big 3. Lots of help, that was.
To get around the quotas, the foreign companies built plants in America that employ Americans. This is not insourcing, this is building at the point of the market place. They do not then ship American built Toyotas back to sell in Japan.
the point is, they build the cars in the US, employing our workers.
