Answer:
Liechtenstein has a market-oriented economy, with general low levels of taxation, and a small safety net for nationals, that includes public education, and some healthcare coverage.
It is also a federal state despite its small size, this means that the municipalities inside Liechtenstein have some degree of autonomy, for example in taxation, which creates competition for investment inside the country.
The central European country only has 38,000 inhabitants, but a GDP Per Capita of 139,000 dollars according to the CIA World Factbook. What this means, is that Liechtenstein is one of the wealthiest countries in the world, and its economic system contributes to that economic health.
