Another way of thinking about that is we only eat 1/4 of what we grow. We export 3/4 of what we grow.
Consider then the SMH getting upset when our supermarkets start selling - the horror - imported food.
It comes as consumer and industry groups have accused supermarket giants of lowering standards of fresh produce, particularly by shunning local growers in favour of cheaper, imported produce.
I remember a concept known as "comparative advantage". If the Chinese are better at growing cabbages than we are, but we are better at raising cattle, then it makes sense for us to import Chinese cabbages and for the Chinese to import our beef. We both gain through this process.
So what is the problem with us importing a bit of food, given how much we export? Remember all that nasty wheat that we sold to Iraq? Remember those poor sheep that we flog to middle eastern throat slashers? Remember all that lovely, expensive seafood that we sell to the Japanese, such as our best quality tuna for sushi?
Another case of those geniuses at the SMH failing to light up the single brain cell that they share.
