The 1990s were a brief window of time during a cultural shift from the right to the left when society was in the center. That period was great culturally but unsustainable because cultural neutrality is unstable. Culture will always move in one direction (left/right, order/chaos) then swing back. We cannot hold the middle ground. The leftward swing of the 1990s continued into the aughts, then went too far in the 2010s and 2020s. A backswing of the cultural pendulum to the right is inevitable. The only questions are "when" and "how far?"
These cultural cycles are common to all civilizations and largely outside of human control. The forces are inevitable. A similar cycle was seen in the 1960s hippie movement, an extreme movement to the left in reaction to the oppressive conservatism of the 1950s and the McCarthy era. But the 1960s leftward swing went too far, so it swung back a bit in the 1970s, which is a “centrist” decade similar to the 90s. But that 70s centrism couldn't last, leading to Regan's more conservative 1980s, which the 1990s reacted to, moving back toward the center.
The current cycle is on the left end of the swing, though there are the beginnings of a vibe shift—or vibe swing—back toward the right. Most Americans are classical liberals and would like the future backswing to stop and settle in a centrist stage similar to the 1990s—and stay there forever. We will likely experience a similar decade of freedom and creativity in the near-future, but, like the 90s, it will not last. It cannot last. The cultural momentum that brings us back to the center will continue right through it to an age even more conservative than Regan’s 80s.
9/11 was a black swan event that interrupted this natural culture cycle. The early 2000s should have been a natural movement further left, but instead the culture moved right (pro-war, pro-patriotism) in response to the 9/11 terrorist attacks. So there was this pent-up leftward energy that was released in the Obama era, 2008+. The culture moved left—then continued going left, much more radically than normal (because of the pent-up energy of 9/11).
Trump was a reaction to that leftward swing, but he wasn't able to move the mass of culture rightward, only his base. So the mainstream kept moving further left during Trump’s presidency and even now the leftward swing continues through Biden. Something is interrupting the natural culture cycle, preventing the healthy swing to the right, back toward the center. Too many leftist ideologues have captured institutions and forced them to remain on the far-left. The cultural institutions should be fluid, able to swing left/center/right with the culture.
Most people are centrists but are being held hostage by leftists in power. So either the centrists must stand up to the leftists to regain control of institutions, or the right-wing will—either taking those institutions by force or creating their own parallel institutions. The majority of Americans do not like the culture of the far-left, but neither will they like the culture of the far-right. Unless the center holds, the right will take the culture—for some time, at least. That is until the natural forces of “vibe shifts” move left again.
