If this hypothesis is true then you would think that the government in place would do everything they can to stop the far right/far left from rising from the ashes of the failed social safety net.
Instead, what we see mostly is the mainstream parties blaming the far right/far left without even addressing the issues that have led to people actually joining their ranks.
Its the same in Europe. Some people say they want a different Europe, mainstream politicians say no.
People then have the impression that their voices have not been heard. What do they do? They vote far right or far left and say: "now, can you hear me?"
But even that's still not enough, because most politicians are only concerned with being reelected, they still don't listen and they even blame the people who now despise the mainstream parties.
I can't understand this kind of logic.
