It's so tricky. You can do most things right like Denmark/Netherlands, then you mess up just one (housing) and the far-right surges. Now you can't import immigrants to deal with your aging population, which means you're on a timer.

Or your neighbor goes far-right (US, maybe eventually Germany/France) and suddenly they start objecting to your internal policies (eg regulating big tech).

Or Russia+Covid combo suddenly inflating all kinds of prices, and again the far right surges.

I think it's going to be a dramatic few decades.

Yes, extremely tricky. Imo the current ruling class just needs to mess up just on thing, because there is a deep underlaying discontent with the subjectively felt way of living in our modern societies. So housing / migrants are just the spark.
