No offense, but you need to get out more and away from your downer friends.
If you were "living in the days" of MLK, guess what, people went to see shitty Doris Day and Elvis movies to entertain themselves. In 1968, some people just smoked dope and thought that protesting was pointless and "authoritarian" and "harshing their buzz".
Yes, activism is down, revolutionary sentiment is down, but we are living in a situation where the 1960s-70s movements fell apart or were destroyed, the remaining organized left was confused about the end of state-capitalism, and unions have become embattled shells of what they were a generation ago thanks to a conscious offensive on the part of the ruling class (union busting) and a terrible tradition of business-unionism in the trade-union movement.
If you believe, as I do, that Marx was correct when he said that the ruling ideas of any age are the ideas of the ruling class, then it is natural that most people are going to generally see history they way they are taught in schools and in pop-culture, politics the way the Democrats and Republicans frame it, and so on. The way out of this is not hoping that, for some unexplained reason, people suddenly adopt different values or behavior and stop playing video-games, but by actively rebuilding a left-opposition in the US and every other country we happen to be in.
Through winning small battles and wining ideological arguments, we can begin to build a counterweight to all the ruling class ideas that permeate our society. If the ruling class says to workers: "Unions only take your money" it only works if there are no existing counter-examples of militant, fighting unions with rank and file leadership. If the ruling class says protests don't accomplish anything, this only works if people aren't protesting or just go to one large protest and expect that their job is done - if people are sitting-in and wining integration or occupying campus buildings and winning demands, then there is an obvious counter to the ruling class arguments.
Also, as the French say, with the eating comes the hunger. When people see that union actions can win, that organizing around radical demands can win, they develop a taste for it and demand more and expect more the next time. People are really demoralized since the early 00s because they have seen one loss after another and so this causes them to become less demanding and more willing to compromise (and liberals in power are all too happy to argue for the most compromised version of any demands). Anything we can do now to show how liberal compromising is part of the problem and build people's confidence through small wins will help train people how to fight and win and this will be what breaks people from accepting their lot or accepting ruling class ideas.
