That's a lot of very different organisations all thrown into the same bucket.
The UN, second only to the EU, has been a consistent champion of the rights of the individual for decades.
The IMF was set up in 1945 (created in 1944) to rebuild Europe after the war. It has been a champion of the poorer countries in the world since then. It has certainly got things wrong plenty of times but it is not a creature of big business or Western economic colonialism.
If we as citizens of the world want to retain and protect our rights and freedoms from those big businesses who act badly and State authoritarianism then we need strong institutions like the IMF, UN and EU.
Do you know anything about the structure of the IMF or World Bank or the fact that an Irish man is an Alternate Director on the 24 person Board of Executive Directors? We are represented in a group which includes Canada and a bunch of other tax havens which is represented by a Canadian woman (can't think of her name) but when she's not available the former head of the Department of Finance takes her seat.
