Ean, the difference between your industry and mine is that the govt don't have the potential to buy a majority of your product to use locally in projects.;)
The U.K. Is in the same **** basket we are here, have a read.
Britain sacrifices steel industry to curry favour with China
12 million tonnes made in uk being swamped by Chinese dumping and zero govt help compared to the USA, now what's their tarrifs on imports?
Now as much as I do buy local ,fisheries included , whenever possible, trawlers are not a strategic industry but steel is. Where was the Owen gun made? What where all the munitions made from? The steel for the last three generations of subs? Maybe not the next but no political context here.;) the plating for the bushmaster and numerous other oz built ADF equipment?
Now if we had a war or even a neighbour with a trade dispute and needed rails or any other infrastructures repaired could we wait for a ship to run a blockade or make it here?
