Answer:
This is FALSE.
Step-by-step explanation:
There were several leftist leaders in Latin American countries and most of them had mixed results in both economic and social development. Last week one of the oldest leftist leaders was ousted from power in Bolivia. During his government Bolivia had the highest economic growth rate in all Latin America and the highest increase in quality of life. It is still a mystery why things ended up so bad. Another countries that had relatively good leftist governments were Brazil, Chile and Uruguay. In Brazil things also ended up very badly, with the former president put in jail.
But virtually every other leftist president was really bad at running a government, we have the terrible examples of Venezuela, Nicaragua, Ecuador, Paraguay, Argentina, Peru, Panama, and probably a few more.
