"Emmanuel Macron, the French president, has announced that he is dissolving the national assembly, and calling for legislative elections on June 30 and July 7.
The French president said that he can’t pretend nothing has happened, that the outcome of the EU election is not good for his government and that the rise of nationalists is a danger for France and Europe."
That’s not the criteria, the criteria is whoever is the loudest in criticizing the status quo. And the far right is the loudest
The far right would make everyone poorer but wouldn’t change the class structure, so they are allowed to exist while the left gets suppressed. See for example how many of the titans of industry in west germany who supported the Nazis got off scot free (or with much commuted sentences) and got to keep their assets. The system works :)
