Where there is a clear exploitation of the workers and privileged revenues are obtained for management and owners. I would say that while there is a lag there is a fairly reliable tendency for organization to develop. This is true in much of Latin America and you see the beginnings of it in Korea, Taiwan, even Hong Kong. There is no reason to think that the process of union organization there will be slower than it was in the United States. If you drop back 100 years you would have said there wasn't much prospect here, either.
All experience shows that unionization is a lot more difficult in agriculture.
There are a variety of reasons. You have a less stable labor force, less stable employment and the possibility of more cohesive action on the part of employers than in the widely distributed agricultural labor force. There is no question about it, agricultural workers are very hard to organize. Also, agricultural employers have been more effective in using their political influence against unions than industrial employers. We see that very clearly in the United States.
