This is a point that has been on my mind very much lately. Left-wing radicals and Marxists in the US have been saying for years that we are isolated because the US economy has been performing so strongly since WWII. If there was economic misery, workers would listen to us.
Meanwhile the East Asian economies have collapsed completely to the point that Thais in the countryside are reduced to eating bark. Meanwhile I have seen no items in the press about worker or peasant militancy in Thailand.
The Mexican financial crisis was actually not the main cause of the Chiapas revolt. It had to do more with displacements in agriculture brought on by a big EXPANSION in the oil economy which diverted peasants into the construction and drilling industries. The traditional economy suffered, while the new petroindustry was booming.
Reality is not black and white. What will cause workers or peasants to think in revolutionary terms is not poverty alone. Other things enter into the mix. The black radicalization of the 1960s was in a certain sense the product of rising expectations. Many of the arrested Detroit rioters in 1967 were employed by the auto industries. This is a very interesting question all in all.
