So to me, it is looking pretty fucked going forward either way. (Interest stays high, or comes down but dollar crashes)
Not saying you should, but I changed my entire portfolio to overseas growth funds to hedge against AUD going to USD20c.
Last 12 months returned 22%, won't be like that every year but I am not expecting minus 25% any year soon.
If I'm wrong, I feel that there will be bigger problems at hand, if I'm right I can retire to a vibrant lower cost centre experiencing growth, eg Cambodia or Vietnam, that's looking like a much better life.
Now that's a bit extreme, but 40 is easy to see, so maybe 20-30 isn't out of the question. But if it does, then the farmers get a bonanza.
In the post-war years, immigrants often pooled their resources and built their own homes. These days most immigrants just want to move into comfortable new homes.
At today's rate, that will likely change and it will end with people loosing their equity "retirements" in their main asset.
That said what happens at the scale of the economy is like talking about an ocean. What an individual fish does is upto the fish.
