What about all the national debt and interest that we have to repay with a reduced dollar
My poor grandkids will be still paying for the party two decades from now
What about it? It's denominated in Australian Dollars...
That's the thing about a floating exchange rate that is so hard to explain to people. For every transaction, there will be winners and losers but often not how you expect. If someone sold their USD to buy AUD when we were at $1.10 so they could lend our government some money, then they are the people who just lost a lot of money if they want to repatriate it - not us!
No-one is creating or destroying Australian dollars when they exchange them for someone else's US dollars - they just change ownership. There are still the same number of Australian dollars out there, regardless of the exchange rate.
As for the doom and gloom, people are forgetting that the benchmark price of iron ore and oil are in US dollars - a weaker exchange rate neutralises a fair chunk of the impact for miners. They benefit from the lower rate in the same way that farmers do.
And regarding the risk of importing inflation through a lower dollar, I was pretty worried about that too - but haven't you heard? There's been a big drop in the price of oil? Couldn't have been better timing to stave off the inflationary effect of the lower dollar and keep the RBA away from the trigger. Not to mention that this is as much a story of USD strength globally - we are in the same boat as everyone else - which means the products we import from europe for example haven't really got much more expensive anyway. So just like the story of China and iron ore after the GFC - we really are the lucky country!
One day our luck will run out - when there is nothing left except degraded agricultural land and holes in the ground - but I still think that could be awhile yet...
