Good riddance to the inbred monarchy.
I think that if I were the new government of Barbados, I would try to keep the inbred Monarchy around such as to get the British to pay off the massive national debt. Then debt free, the new nation of Barbados could say good bye to the 100 year old Queen and say, thanks for your help, live long and prosper. And maybe set up some sort of trade deal with England to get lots of zero tariff goods flowing between the 2 nations. Hopefully, Barbados will not become a narcotics nation in order to balance the budget.
In short, the relatively benign state of the island today is a rebuttal to those anti-colonialists who universally condemn the British Empire.
The emergence from the British Empire or Commonwealth should have little practical effect on the everyday lives of the Barbadian people but it does reflect a growing international skepticism toward the Royals.
In many ways I confess I am a Tory Victorian at heart even as I pursue populist principles so I regret the inevitable decline of the House of Windsor brought about by self-inflicted wounds and character defects yet I understand that if the Royals were to abdicate today the Brits would have to run out tomorrow and hire another set for the American tourists.
