Total plonkers, you have no idea what the Lima Declaration was.It was not a treaty and was not binding on UN members at that time, but was endorsed by the vast majority of industrialized countries as well as developing nations .Over the next decade it enabled the further development of UNIDO which was started in the mid 60's.In simple terms it had as its aim that developing nations[mostly post colonial agrarian ] would achieve 25% of world industrial production by the year 2000, not exactly revolutionary. This was to be achieved by lowering of tariffs and development aid. Pretty irrelevant by the mid 90's as private enterprise [ you know, that thing you righties hate] had largely taken over. Now we have lost a lot of manufacturing jobs in Australia since , but interestingly Australia has been a big beneficiary of the freeing up in trade and world growth that has occurred since then [with a small contribution from the underlying principles of Lima]. If you are going to blame anyone for that increased prosperity, blame Hawke/Keating by the way, not Whitlam.
Unfortunately , not all of those benefits have been shared equally , as shown by the increase in income inequality , lower taxes , and suppression of wages growth , decreased share of national income for wages vs profits. Essentially from policies pushed by the sort of right wing governments that you lot support.
