Broadly speaking, people fall into one of two types.
Providers and Takers.
The Providers create. They make stuff that people want. They innovate, they invent, they fix, they organize, they optimize, they make, they provide essential skills and services to other Doers.
The Takers merely consume what the Providers create and sometimes, not always, serve as useful labor to carry out the goals of the Providers.
The Providers create the vast majority of useful goods and services. This in turn gives them wealth, prestige and power. The reason they have more is axiomatic to the Providers. They would be puzzled if asked why this situation exists, for the reasons to them are self evident.
The Takers usually occupy the lower strata of society. They are less wealthy, and less respected. They are usually incapable of understanding their position in life, they have neither the intellectual capacity or pragmatic education to understand that in the grim reality of life it is the Providers who are more valuable than themselves. This part of the social contract is simply incomprehensible to them. You may as well be try teaching quantum mechanics to a cat.
Envy is a powerful human emotion. Those who perceive themselves with less will always be seeking to usurp the power and wealth of those they see as having more. The Takers will always be attempting to take the position of the Providers.
What we are seeing is a tipping point.This is how a revolution of the masses against the rulers takes place in a democratic society where out right revolution is neither practical or desirable. Instead it is done by stealth, infiltration, and creeping socialism.
It is not a conspiracy. It is not being "organized" by someone or group. It is the inevitable result of what Marxists would call "class warfare" and conflicting economic factors operating in our societies.
Its all merely a normal cycle in human society which undergoes steady changes in human hierarchies.
