My post was rather toungue-in-cheek.
The British left many of their colonies in a better state than when they arrived.
In India, for example, in December 1829, Lord William Bentinck, the first governor general of British-ruled India, banned sati, the ancient Hindu practice of a widow being required to throw herself on her husband's funeral pyre to burn to death.
The British also banned the sacrifice of new-born babies to the goddess Kali.
In addition they built schools, roads, railways and introduced law & order and medicine.
In the 6 months to June of last year Vietamese made up the largest % of small boat arrivals to UK. Vietnam is not and never has been a British Colony. It became a French colony in 1858.
So go figure that one out.
You should do your some research before you post such uninformed material.
