In Sri Lanka, the window for saving the post has probably closed. According to the latest Household Survey, a Sri Lankan household spends LKR 4/month on postal services and LKR 750/month on telecom services. You cannot build a viable business on that kind of money. There will always be a need to deliver packages (until teleporting is perfected), but this can be done by agile courier services, not the bloated government post office. Now that the US postal service is almost bankrupt, everyone is looking at Europe.
