Playing the leftist liberal role here: It depends on your point of view if you can call a person/group of people 'savage' or 'civilised'. In the general 'Western' policies, ideas like 'civilisation' (not so much used anymore) or 'development' are seen as the manner in which a country, etc. is 'western'. I.e. if a country has a capitalist system, if it has 'modern' healthcare, has Coca-Cola, and such. This means that attempts by governments, development agencies, and such, in their every-ongoing quest to bring civilisation to the Third World, try to make other countries as much 'western' as possible. By for example blasting them through two hundred years of industrialization in a couple of years.
In my opinion, terms like 'savage' or 'civilised' (heck, even terms like 'development'), are some of the most meaningless words in the English vocabulary. There are so many definitions and views on what these words should mean that it is difficult even to debate them as everyone has a different opinion about it. Overly generalizing example, but go to China and the Chinese will probably say that China is the pinnacle of human civilization. Go to the US and they'll say that America is the greatest nation on Earth. Etc. etc.
In short, the terms 'savage' and civilised' mean different things to different people, and imply that some people are better than others just because they have different practices, norms, values, etc. Though quite popular in Conrad's time (with Britain conquering the world and such) I don't think that anything meaningful can be said about being 'savage' or 'civilised', that has some universal relevance.
Edit: Woops, this ended up a bit longer and complicateder than I wanted. Probably should procrastinate with CYS while writing essays and such... :P
