Yes, Burnham took a stab at nationhood. My recollection - Indians for the most part wanted no part of it. They even vilified the Indians who tried to promote Guyana as a nation.
Realizing the importance of minimizing debt, Burnham promoted FCH - feed, clothe, house the nation and emphasized the use of local products. Buy local, eat local, etc. Great ideas, but not executed properly. However, the intention was commendable. We see how the lack of such has devastated the nation. Today, every government is scrambling to set up local industry to no avail.
How did Indians respond to FCH? They saw it as "discrimination" against them. Burnham didn't want them to make roti. Well, didn't black people make bread with flour too? Weren't we likewise affected? NO, the Indian saw only himself as the victim!
Granted, FCH was not well thought out and rolled out too quickly, before local substitutes and/or alternatives were identified.
And yes, Burnham's good intentions were overshadowed by his megalomania.
