it's good to see you agree with me even though you do not seem to know enough economics to know why.
A major reason that Australia secondary industry cannot compete is that the exchange rate makes imports relatively cheaper or offshore secondary processing cheaper..
I recommend that you read the link that I list below.
Iron ore and the Australian Dollar: Two Peas in a Pod?
The period of $1.50USD exchange rate coincided with the death of much of our secondary industry . You think that is coincidence?
The export of Iron ore and coal dragged the exchange rate up to heights where no other industry was competitive with imports or competitive in export markets.
It is only the extractive and primary industries that have remained competitive as they set the exchange rate and we generally have a freight advantage over competitors such as South America.
Its a fact not BS. It is true the car industry was featherbedded far too long but even Toyota could not make money here at the exchange rate . It's impossible to know but I reckon Toyota would still be here if the exchange rate was back then as it is now.
