This is difficult to project. If the escape valve was not there, Guyana would have been a different country and have different leadership. For example, Caribj would have been a PNC top dog and the geriatric crew long retired!
Those of us who migrated would have buckled down and made the best of it, in business and professional. The population would be larger, so would the economy. The country would be more developed.
So to project into today’s Guyana the what if is an oversimplification! You need to simulate more wholistic!
