Well I'm hoping for what it's worth:
More manufacturing will return to Australia (favorable financial policies provided).
key industries like food, water, power etc. will have a restructure & their importance elevated to an appropriate level.
People after going through the "shock" (yes i know how can people be shocked when they spend more than they earn etc.) of this financial tight rope will re-access whats important, the difference between a need & a want etc. & come down to earth a little.
People having seen being overly dependent on other countries for items will consider buying locally more often, if the locals can compete on a more level playing field.
People may have encountered more acts of human kindness & are willing to "pass it on" a little more frequently or just become a little more tolerant of others.
Generally I'm hoping as a country we will work towards being more self sufficient, greater security within the food, water & power sectors, provide opportunity's for our own to research, invent & produce here, with the Govt creating a more conducive environment for all this to happen. Yes change is slow, times will get tough but Australia has been through some hard times & the people are a pretty resilient lot.
I know Its very non specific, pie in the sky stuff but one can always hope, right !
No the other hand we can always hope for peace but plan for war.
