Raise some interesting points Ryan. Certainly is going to be some disruption.
Close to home Ford (Geelong, Victoria) and Holden (Adelaide) are scaling back massively or closing altogether their car manufacturing.
Personally I believe an unemployment benefit safety net, plus access to free training programs, counselling etc is the answer. Also interest free small business loans etc. The longer standing employees, will also get nice redundancy payouts - it's important they use that cash in a boringly good way - pay off mortgage etc.
Don't see an UBI as the solution.
