That’s an interesting theory and I certainly think the difference in the way we access information plays a role, but I don’t think it accounts for the stark contrast in media reporting between Obama and Biden. I don’t think things got bad for the elected the moment Trump became a serious candidate and then became good again the moment Biden took office; however, that’s roughly the portrait the media gave us. Trump comes into office and basically continues Obama’s immigration policy and suddenly we have an immigrant crisis and America is a white supremacist hellscape. Trump leaves office and (barring the Jan 6 riots) America is peachy-keen per the media. It certainly seems manufactured, but not by the government and not reflecting the discontent of the elites. I genuinely don’t have a good hypothesis to put forward. :/
