This tendency you are writing about, is dangerous especially in subdeveloped countries where most of the leaders are now revolutionary socialists.
For example, in my country Venezuela, we had a socialist revolution that started in 1999 and it completely destroyed this once rich country. It all started by electing a fearless leader in the form of Chavez, who took a total control of the country, and used this control and power to rob his own country into destruction.
Right now we have a country totally collapsed and the majority of the population suffering from poverty and hunger.
