In defence of Colombians...
In every section of a country you get good and bad citizens. Most Colombians earn an honest living, providing taxes to the government, and high rates depending on the area they live. Also, some of them provide employment or work in the private sector, which is the engine of the growth. Some of the Colombians are good philanthropists and social workers who go to rural areas and help the poor, protect the environment, help with animal welfare, aid hospitals and many other worthy causes.
Why not mention and bring awareness about the corrupt politicians, drug traffickers, sand miners, tree fellers, illicit liquor brewers and the informal sector that pays no taxes and living a life of luxury and thereby ruining the environment and the younger generation. If there is proper law and order and the inland revenue plays its part, then most of the offenders will not be the Colombians.
Duty-free vehicles and perks are given to the politicians and their stooges. Even these are funded by tax payers. If a country ignores and harasses the city folk, then the educated, younger generation will migrate. What we need is to not differentiate the sections of the people, but to unite the country to one single identity as Sri Lankans. R.DE MEL
