There are a lot of places around the world that fit this mold-- their economies are healthy and people are legitimately confident about the future. From Estonia to Hong Kong to Andorra to Singapore, there are common elements in these countries that have greatly contributed to their success:
1) They're small.
2) They have governments that generally stay out of the way.
An obscure 20th century economist named Leopold Kohr wrote extensively about these factors; and his 1957 book The Breakdown of Nations has proven quite prophetic.
In the book, Kohr extols the virtues of 'smallness' and indicates that most of the political challenges in the world-- military over-extension, debt, poverty, bureaucratic stodginess, etc.-- are caused by the unsustainable expansion of nations.
For Kohr, it is simply a matter of scale. Once a country becomes too large, any system of government will become oppressive.
Small countries, conversely, don't have the resources to wage wars or build huge bureaucracies. They're forced by circumstance to allow the market to work and the private sector to flourish.
Singapore and Hong Kong are great examples. They're not waging wars, dropping bombs, or establishing far flung military bases. Both countries are devoid of any natural resources, and their only means of survival and success have been to step out of the way and let the market take over.
In a matter of decades, they have become two of the most prosperous nations on the planet, and remain among the healthiest today.
Conversely, the 'big' countries of today have assembled massive states which have spawned massive governments that require massive resources to administer... and quite oppressively I might add.
Democracy may look great on paper, but in modern practice of today's 'big countries', it is a terrible perversion of the principles of liberty. Like Rome and the Ottoman Empire before, the individual now exists to support the state, not the other way around.
This is exactly what Kohr warned would become the 'crisis of bigness'. Faced with economic challenges and a debilitating cost structure, big governments and bloated bureaucracies will only beget more bigness, more bloat... until the only possible outcome is collapse.
It reads like a playbook of exactly what's happening today in the west. Already suffocating from too much debt, governments are going deeper and deeper into debt, and hiring more and more workers to administer 'stimulus programs' and an ever-expanding tax code.
To politicians, the solution is to expand the state and expand their authority. This is the exact opposite of what they should be doing... and as has happened numerous times throughout history, it may very well lead to an entire system reset.
