I think you get that wrong. Trump and Brexit are the direct result of democratic decisions in countries with a long history of democracy. Denying that isn't helping.
Yes, democratic decisions resulting from massive propaganda campaigns, funded by some extremely wealthy personalities. Obviously the problem here is democracy, not the very few overtly corrupt and overly powerful people undermining it.
And these overtly corrupt and overly powerful people exist within old democracies. You might have a nice and naive imagination of what democracy could be, but you shouldn't deny what it is RIGHT NOW.
