With regards to the PPP or PNC, both had/have their flaws, the PNC more so based on the massive brain drain that occurred under their watch. The very nature of the Guyanese economy has much to do with the brain drain as it dictates the opportunities available. An agricultural/mining/lumber economy will not have sufficient opportunities for those with academic aspirations.
I laugh when you pretend that a nation whose largest industry produces people who are waiters, hotel cleaners, taxi drivers, and hotel check in staff will offer more opportunities for educated people than one with a resource based economy.
Druggie your excuses are deplorable. There is way more scope for highly trained technicians in the natural resource based economies than in those based on tourism.
Using your criteria then the PPP is a colossal failure. In 2012 less than 8% of Guyanese over age 15 had completed tertiary level education, and in fact only regions 4 and 10 had levels higher than that. In the famous PPP stronghold, region 6, only 5% had tertiary level education.
Even if we add post secondary education which doesn't lead to a university degree less than 3% attained this, again with only regions 4 and 10 exceeding this.
So less than 11% of Guyanese over 15 had completed any form of post secondary education. Interesting to note that 16% of those in Region 10 had completed this, due to the high numbers involved in some sort of technical training.
Barbados had 17% with university degrees and 11% with other post secondary education.
Meaning that just under 30% of all Barbadians have completed some form of post secondary education, vs. less than 11% of Guyanese. Antigua, which does NOT have a university available to locals (it does have off shore medical schools for Americans), has 22% with some sort of post secondary education.
Note that the PPP had been in power for 20 years when the 2012 census had been completed.
