our dollar should be 60 cents

That's right, 6o cents against the US dollar, not currently high 70s.

China is getting all the benefits from fixing their currency at a low level against the US dollar. By contrast, our balance of trade and our exports have been hit. We should we having a positive trade balance with the current high resource prices.

The government should fix the exchange rate which would immediately put an end to our dollar's rising against the US dollar and make us again competitive.
