Globalization played (plays) a huge part in this timeline too. If I can outsource your job to a place that really does treat their employees as disposable, you should just be happy to be employed. And even if I don’t want to offshore, how does my product/service succeed or remain sustainable if my competitors are all offshoring (or indeed come from offshore)? I’m not defending this attitude just distilling and illustrating through extreme language what I see as a reality of global competition.

Post-WW2, America had a lock on global manufacturing and was like last man standing in a burned down world.

It was/is an illusion to think that could be a permanent state.

The pre-war employment situation in America looked nothing like post-war. Your race to the bottom narrative is probably better framed as reversion to a multi-polar world with bonus features of higher global prosperity and capability, lower barriers to access foreign markets (whether laborers or consumers), and mature logistics infrastructure. In short - more people than ever want YOUR job, and to live in YOUR house, and have YOUR safety net, such as it is, it’s not just some focus on quarterly reports.
