It'll likely get worse as idiots double down on either side.
I think a big part of the problem, at least in the USA, is that both sides are pining for an America that no longer exists and cannot, in the foreseeable future, be recreated: The America that existed between 1945 and 1972.
There were a lot of factors that are responsible for why that time period was so good for so many:
-In 1945, America was at the zenith of its international prestige. The USA helped defeat Hitler and Mussolini, and while all that was going on, stomped Tojo pretty much singlehandedly. Far from being decadent isolationists, America stepped in and saved the free world by smashing fascism west of the Iron Curtain and containing communism behind it.
-America was militarily unassailable. Germany and Japan were utterly defeated. The Soviets didn't discover the atomic bomb until 1948, and had no means of delivering it until the Tu-95 bomber became operational in 1955. The USAF ruled (and rules) the skies. The USN ruled (and rules) the waves with the most, the biggest and best battleships, cruisers, destroyers and aircraft carriers. Her submarines rule the depths. The USN is also the world's 2nd largest air force. America could go wherever she wanted and nobody could stop her- the Red Navy was a joke and the air force able to defend territory but not project power.
-Oil. In 1939, the USA produced 70% of the world's oil supply and had the world's largest tanker fleet.
-Production capacity. After WW2, newly built or expanded plants began producing civilian goods. The USA was the only major industrialized nation to not be severely impacted by WW2- Canada and Australia were too small to be much competition and were often home to US branch plants. Britain was battered, Germany and Japan devastated. France and Italy relied then on lots of semi-artisianal workshop labour and could never really compete. China was largely undeveloped and the Soviet Union was an economic mess. America had no real competition.
-Labour processes were much less automated and much more labour intensive than they are now and needed a huge unskilled worforce to draw upon.
Long story short, the rest of the world caught up and industrial automation charged forward, but politicians didn't- and don't- know how to deal with it.
