Sorry, I must have misunderstood you. I thought you were saying the world has been moving steadily rightward (which, in my observation, it sadly has) and there were so few examples of things moving to the left in any country in the past 50 years considering corporations are the ones actually pulling the strings.
It has been moving steadily rightwards. What I meant is that at no point in the last 60 years has any far-left group forcibly taken power unlike far-right groups.
