7. BUrnham and the PNC banned many imported products during the PNC dictatorship.
I would like to step in although the question was not addressed to me,the banning of selected food items was a measure taken by the dictatorial regime in that era,was due to the country lack of foreign exchange,that move was not welcomed by the people, notedly the East Indians, some of the items was their regular diet,from then on the measure that was taken,became a political spin.
Regarding the rest of your question, an economic development was created,it was not legit,it was an underground economy,the illegal food trade mushroomed,even fuel was on the list,to bolster the illegal activities illegal foreign exchange and corruption of the security forces increased,thinking about these events,Burnham created the run away society.
Nonsense, banning came from the "feed close and house the nation by 1976" mantra by kakaba. While his intentions were admirable, he targeted the traditional foods of the Indo. In fact he may have contributed to the thirst for foreign products inadvertently. When you take a toy away from a child, he/she wants that toy even more. Had he not banned foreign products, Guyanese may never have scorned their own local products which became their only choice.
