The answer to the question posed by the headline is simple:

The elites have built a propaganda machine / mind control device called "Social Media". Facebook, famously, sought to determine if they could influence people's emotions. They succeeded in manufacturing negative sentiment. This was then harness by the "elites" to wage class war against the rest of us.
