Was the soviet union necessary to the American middle class?

In 1917 the US was rapidly industrializing; the rich were getting richer, the poor, poorer and the middle class of tradesmen were being decimated trying to compete with no skill labor in a situation that has much in common with today. However, half a world away the October revolution was on, and a scant seventeen years later the power elite in the US suddenly cared about the starving elderly and restoring the middle class.

Prior to the industrial revolution, the middle class’s position was assured because it took skilled labor to make goods; however, that is no longer the case. Until recently all it took was a handful of skilled technicians to set up and maintain the machines and all the work was done by unskilled low wage labor. However, the factory workers were well paid even though third world peasants could do it for nothing, why? Did the soviets hammering away about how they will bury us, and strangle the last capitalist with rope he sold them have anything to do with it? Personally, I have never felt compelled to purchase insurance to protect against things I don’t think possible. Prior to the 80’s a soviet takeover leading to the near instant executions of all our elites seemed possible though improbable.

Was the Soviet Union a necessary condition for the existence of the middle class as we know it today? If so we will probably have a revolution because the restraints against rapine are gone and today, with plant automation we can even dispense with the unskilled labor, all it takes is a handful of stilled technicians to make unlimited amounts of product.
