With more than 70 years of post-war experience in a wide variety of modern democracies, a lot of things have been tried out in a lot of countries in nearly every domain of public interest, like public health care, pensions systems, handling of unemployment, internal security, education, transportation, energy, consumer protection, laws of labor, etc etc.
Although of course every situation is different and different solutions might apply in any given context, there is consensus imho that some countries do better in some of these areas than others. There also some pretty universal indicators, that together with the financial efficiency can be used to rate every domain. Finally there could be opinion polls in the population on how they judge their own health, education, etc systems in order to rate them in comparison to other countries.
Then the idea is just to copy the more successful systems in one's own country. Domain by domain.
For example there is broad consensus that - France' health care system is one of the best (as stated by the WHO), - Finnish children score high on education assessments, - Switwerland's national railway system is one of the best.
So why wouldn't any country modify their legislation in order to copy French health care, Finnish education and Swiss railways? (Examples might be debatable, but you get the point)
Are there any systematic efforts in politics in any country to learn from other countries and just copy their solutions to domains in the own country where these solutions are applicable and are likely to provide better efficiency or satisfaction?
Why hasn't each country a "Ministry of copying foreign countries solutions"? Why don't we hear more political parties programs say "For [this domain] let's just do like they do in [that other country]"?
The idea is especially appealing for Europe, where there are many modern democratic countries that share a similar development level and face similar challenges, but with a variety of individual solutions that have or haven't worked out in the same way.
