Yes, all true, but in many respects, what is happening today is worse than all of that. See below.
Well...this would certainly be one of those sinister undertones I mentioned. News is now, for the most part, self-consciously about creating a propaganda narrative that few people see through. While there was plenty of propaganda going on in the 50s and 60s, it wasn't as bad.
A few points:
1. We have police shooting unarmed, non-resisting human beings rather frequently these days, and sinister undertone number two (number one was the point about news, above) is that we've become numb to it--they get away with actual murder and we continue to do nothing.
2. I think we could match mass murders today with riots in the 60s and 70s and get pretty close in number and frequency of incidents, and a considerably higher body count these days...and sinister undertone number two comes back into play. The '68 Chicago riots involved lots of really angry people (and hence are more impressive at first blush), but relatively few injuries and no deaths. The Charlottesville demonstration/counter-demonstration is comparable in a number of respects, except that while no one died in the Chicago riots, three people did die in Charlottesville (Heather Heyer and two Virginia State Police troopers who died in a helicopter crash whose cause has yet to be established, except that we know it didn't collide with anything mid-air).
3. The major issues that confronted us in the 50s and 60s were racism and the rise of the military-industrial complex and attendant corruption. The major issues we face today are wealth inequality, environmental devastation, and a decay of our social fabric.
Protests and legal action against legalized racism and discrimination (i.e. Jim Crow laws) was bound eventually to work in the 60s because the necessary individuals had realized that the founding assumption of racism--that non-white people aren't fully human and hence are not entitled to equal protection under the law--is false. So, despite massive entrenched social forces, the repeal of Jim Crow and enforcement of equal rights was bound to take place.
On the other hand, the principles that underlie our Constitution and our economic systems actually protect wealth inequality and also protect the social institutions that destroy the environment. Back in my corporate days, when the effects of the Kool-aid were still pretty strong for me, I witnessed and participated in policies and actions that short-circuit market economics and reduce the power of workers in ways that most people would consider downright evil--but the rub is that they were all entirely legal, and protected by the Constitution, as it turns out. It is very unlikely that we will be able to confront these issues in time before they lead to massive disruptions...and sinister overtone number 3 is that news sources typically avoid giving these stories coverage proportional to their threat, and in fact corporations even now interfere with primary education to make it less likely people get the kind of education necessary to figure out what's really up.
