That's very true. I grew up in Sri Lanka so I have an idea about how its educational system works. From an early age we are taught to think that we are the centre of the universe and that "Sri Lankans lived in cities and built lakes when others were wearing leaves as clothes".
When I came to the UK, it was quite a cultural shock to find out how irrelevant we are. Unfortunately for most people who grow up in Sri Lanka, this same mentality persists. Now coming back to investments, Sri Lanka is not a super duper country where everyone is bending over backwards to invest. It has to compete with other countries in the region to receive investments. It can't afford to throw away what little opportunities it got like in the case of Port City. Well, if it can't even keep the investments that it got without much competition, how can we expect it to compete with other countries for investments? There are many other countries in the region that offer much better prospects than Sri Lanka. If I am an investor looking to invest in the region, I would definetely not choose a country where my investment gets threatened because of government change.
