Just discovered this video from a comment you left on one of my videos from several years ago

Please do a video on your new magnetron ! loving the content.

The population collapse was a regional thing, more than global. I think people did not died out, but moved to other cities. Like northern Germany to south, when the coal and steel production was no longer attractive, but the car industry was exploding. I'm not sure if it is energy, or industry. When now the whole automotive industry moves to china, with electric cars, It will be interesting to see what happens...

It's 100% outsourcing and foreign sources of production. It's still happening today. Here is an example of the same thing happening in Canada. When wages decline and cities and states don't lower taxes and market prices do not adjust accordingly, then people just leave because they need resources (money). Yes, it's just a transfer of wealth in one direction ... Asia (Mostly China). The video is an example of north American loss of competitiveness with china. And it's mostly western powers who are losing sources of production (jobs). We know the skill required to make machine tools. But since labor rates and regulation is not accommodative, (doesn't adjust) we lose they win and another machine shop (or coal plant or steel facility or tool shop) goes bust and a few more people leave to find new jobs. Enjoy the decline. Just think about it, our economy needs somewhere between 1 trillion to 5 trillion to grow ... and that's all borrowed money. The borrowed money doesn't go into newer and more efficient means of production, it goes into wasteful spending managed by people who are not in business and not spending the resources carefully. Hence, we get more debt and less of our own resources in our hands to spend in a efficient manor.
