How is the wrong conclusion result in necessary condition not in the sufficient condition?

This is often heard that the market institution must not be used based onto the fact that several countries are market economies but remain poor. The cause this logic results within a wrong conclusion is which they did not realize the adoption of a market mechanism is just an essential condition for a country to be rich, although is not a sufficient condition. Becoming a moneyed country also based on other factors as like political system, culture and social infrastructures. Additionally, no illustration of a country can be established so far that this is rich in the long run, which is not a market economy.

The positive statement state fact whereas normative statement provides opinions or value judgments. Differentiating these two statements can void many needless debates.
