Natural resources are overrated, human capital is vastly more valuable. The EU has a large, highly educated population with stable civic institutions. Sans another major war, Europe will be fine.
I've had many arguments with people where I can't get it across that it costs a lot to get a human being all grown up, socialized, educated and ready to work in high value industries. Then we get them swept away to the west (and for good reasons, more money, higher quality of life etc.) and end up with nothing for all our societal investment. If we're lucky, some of them come back with some know-how and create a viable business, but most don't bother.
3 / 4 of the people I went to school with (primary, secondary, high school and college) are now gone for good. Almost as many upcoming graduates (soon to be 18+) are planning to either study here and go, or just go.
This pains me as someone that decided to stay behind and try to change something. But I do understand their motivations.
Resources are nothing without people.
For now. Take a look at those demographic age pyramids and sub-replacement fertility rates. What's the population of the EU going to be in 2100?
They are overrated until you don't have any. It's hard to manufacture anything without natural resources. It's hard to heat your home or fuel your car. As far as the "stable civic institutions" the farmers in the Netherlands would like to have a word with you.
