The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum....
In his book "The Common Good," Noam Chomsky discusses the mechanisms used to maintain social control and compliance among the populace. He suggests that by narrowing the range of acceptable viewpoints, authorities can foster a facade of free discourse while minimizing dissent. This strategy keeps individuals engaged in spirited debates, but within predetermined boundaries that prevent any significant challenge to the status quo.
Chomsky emphasizes that this manipulation of public opinion serves to maintain power structures. By confining discussions and limiting the acceptance of alternative ideas, those in authority can easily suppress revolutionary thoughts and ensure that the general public remains passive and compliant, thus safeguarding their interests.
