And to make that happen:
- The gilded age made some robber barons insanely rich (though not as rich as the current American oligarchs)
- There was a huge economic crash, called the Great Depression, during which the excesses of the rich were incredibly unpopular and the rich felt in real danger
- To get out of the Great Depression, the US Government created all kinds of "socialist" programs to help people get back on their feet, strengthen unions, regulate business, make massive investments in US infrastructure, etc.
- Right as the Great Depression was ending, WWII began
- For a while the US was "neutral", and was manufacturing war materiel for the various countries at war, though mostly for the Allied side. This involved huge amounts of government spending.
- Then, a few years after WWII began, the US entered the war, and spending ramped up even more.
- Virtually every other modern economy in the world had its infrastructure destroyed during the war. Britain was bombed relentlessly, Germany was flattened, Japan was nuked, France was turned into Rubble, the USSR's factories were destroyed as Germany advanced and partially rebuilt in the middle of nowhere.
- The war ended and while every other country was rebuilding their shattered infrastructure, the US infrastructure was running hot and able to supply the world's needs
- American workers were massively in demand because it was almost the only remaining industrialized country with intact factories
- American workers still retained the massive worker benefits and union membership that was the result of the New Deal economy
So, take that sequence, and for a brief moment a white, male worker in the US could support a family on a blue-collar salary in a way they hadn't ever done before that. Once other countries rebuilt their infrastructure, the US lost that edge. Once American businesses pushed for the roll-back of worker protections, blue-collar workers lost that benefit. Bit, by bit, the world returned to the way it has normally been, where the lowest class barely survives and both parents work hard, while the rich benefit.
