Within the next 10-20 years the entire country's infrastructure will decline immensely because of lack of proper replacement and maintenance of bridges and railroads.
Basic access to healthcare is still shit, especially if you consider other Western countries.
Something with taxes, as in raising them, may go a long way. Sorry guys the issues in your country are mounting so fast y'all need some socialism.
