My recollection is different. The Portugese, Chinese and wealthy Indians (a significant amount of folks) did not favor nationalization, in so much they fled because they feared it would cost them their businesses. Secondly, there were those (mostly middle class blacks, portugese and "red" man) who held high positions at Bookers etc. and were quite comfortable. They too did not want Burnham or Jagan running things.
The support for nationalization came from the hoi polloi who didn't know what marxism, socialism or anything meant. The average canecutter, black laborer / civil service worker were clueless. All they heard was there will be freeness thru socialism, so they wanted it.
Another instance where educated Indians, blacks, portugese and chinese were united in their beliefs.
Yes, this is a fair assessment and I recall something along these lines, but what percentage of the population do you think this "group" comprised?
