> That only leaves France and Belgium. Did they do well?
Looking at France and the quality of their industrial output in the 70s to 90s, ranging from high-speed trains, rockets, passenger airplanes, Concorde, helicopters, (racing) cars, submarines, nuclear power plants, medical labs, etc. I would say yes. Their infrastructure has also been of high quality, so has the education system of their elites, and their healthcare.
And from what I could see of Belgium and their infrastructure, it also looked like that period was good for them.
> Modern healthcare is better than anything before. Even in its dysfunctional state it is better.
This is a more relevant point. The question is if we aren't well past a point of diminishing returns. For instance, for France, the data shows that the life expectancy of women was increasing by 2 years every 10 years, until 2010. It has increased by 0.5 years since then. The life expectancy of men followed a similar trend.
In fact, we might not have seen the full effect dysfunctional health care just yet, and we could be riding on the momentum of previous gains. And the ever increasing delays to see a specialist can only have detrimental effects in the long term. In parallel, the disproportionate increase of healthcare costs per patients means that, at some point, life expectancy is going to go down.
> One of the reasons is that our requirements for those services are much higher leading to much higher inherent costs.
No, I don't think I agree. The house you are getting has not improved 3 fold in quality compared to 20 years ago. The roads you are driving on are not 2 times better. Train travel is not a lot safer, nor faster, nor with more frequent service. On the contrary. The food quality in your supermarket has not improved. The electricity you use still has the same voltage and the same frequency. The clothes you wear are not of higher quality.
