'Third World' -- I hate this term.
Where does it come from?
- Cold War & Bandung Conference: supposedly being non-aligned to the socialist or capitalist world
- 3 Worlds Theory: 1st world is big imperialists, 2nd world is wealthy allies of 1st, 3rd is everyone else
Both of these are bad ideas for various reasons.
There are also lots of countries, which it would be hard to fit into any of the 3 categories (using either schema).
Also, the term 'Global South' is dumb too. Australia is in the south. Albania is in the north. Case closed.
I think that in current usage both these are simply a way of creating euphemisms, so that one need not mention things like 'imperialism' or 'national oppression'.
I always wondered about this term, especially since most revolutionary communists reject the Three Worlds Theory, yet constantly use the term "Third World". Hmm... what to do?
Well I'd suggest talking about whatever country or region specifically i.e. 'South Asia' or 'Bolivia'; or the characteristic that unites them i.e. 'oppressed', 'neocolonial', etc. Also one can say 'countries like X'. So we could say, 'People in oppressed countries like Bhutan suffer from domestic feudalism as well as foreign imperialism'...?
There is also the word 'underdeveloped'. This is different from 'undeveloped', which implies a simple lack of development. 'Underdeveloped', on the other hand, understands that there is an active process which keeps the country & its economy down. This is a bit academic, so maybe not for agit-prop posters, but at least for papers where we want to have scientific accuracy I think it is a perfect term.
