It's fabulous that the land of Costa Rica and it's inhabitants are the happiest on the planet, as measured on a limited criteria.
But how hard can it be to make the decision to abolish your defence forces and throw the saved money into education when you only have a population (at that time, even fewer) of four and a half million people?
With a rate of urbanization of around 60%, one of the highest in the world, and beautiful beaches, no wonder the natives are happy chappies.
So, yeah, on ya Costa Rica, but the rest of us can't appropriate your way or scale of life. Sucks for us.
