It is the lack of productivity growth that is causing a lot of extremism and conflict right now. Large groups of people feel that the only way for them to win is if others lose and vice versa. That's a recipe for disaster.
The key question is what happens to those who lose their jobs. Will they find other, perhaps even better, jobs? Will they get a piece of the growing pie even if they don't find other jobs and have to retire early?
It's these eternal political problems that we have to solve. It's nothing new. It has never been easy. But it's probably easier than managing decline and stagnation because at least we would have a growing pie to divvy up.

It is a bit like claiming that third world low productivity countries are suffering because there are countries with much much higher productivity. Well, they can continue to do low productivity business but increase it a bit using things like phones developed by high productivity country elsewhere.
No. A country has its own territory, laws, central bank, currency etc. If it has sufficient natural resources to feed itself, it can get by on its own (North Korea comes to mind).
Individuals unable to compete in their national economy have none of that. Do you own enough land to feed yourself?
