The unions also provide other benefits. For example, most of them own summer houses that any member can reserve to go spend a weekend away. You rarely hear the average Icelander on either side of the worker/manager divide complain about them at all. Everyone more or less views them as beneficial.
Once or twice a year they make headlines when one group of workers or another feels aggrieved and it escalates to a brief strike in some small sector of the economy, but on the whole, I don't think many Icelanders would trade their system of employment for ours.
Like so many other areas, I think the problem is that we in the US are just so very much worse at running our society and country than most other comparable countries. Look at health care. No one liked the ACA; no will will like the AHCA or whatever the Republicans pass. The problem isn't that it's impossible to do a decent job at a health care system. The problem is that we specifically suck. Put us in charge of anything, and we'll turn it into something awful that doesn't work, but provides some brief period of outsized shareholder value.
Actually, it's 1000x.
So while the EU plugs away making incremental improvements each year we keep jumping around in fits and spurts forward and backward. There is still a strong belief of American Exceptionalism even in fields where we are clearly inferior. Look at Healthcare Europe figured something out that we didn't and their is cheaper and better.
As you "scale up" in diversity, population, and geographic distribution the set of things people can agree on falls off dramatically.
Iceland has a very divisive political system at the moment. The ruling government has been a coalition of the Progressive and Independence parties, roughly the european versions of the social conservative and pro-business factions of the Republican party respectively. Though it should be said that no one in Iceland really touches quite how regressive American social conservatives are. And, of course, being (sort-of) Scandinavian, there's a massively strong Social Democrat/Pirate/Left-green contingent in the Reykjavik area that can't stand the agenda of the main ruling parties.
Iceland doesn't function because they manage to get people to agree more than Americans do. There are something like 13 political parties in an average election, and they stand in bitter opposition to one another across a huge variety of issues. Iceland functions because they make their government function anyway. Nothing about being small makes it easier for two opposing parties to somehow figure out a way to get the damned bills paid. You could replace the entire American republic with Donald Trump and Barack Obama, and we'd get no more done than we do today, because the government isn't trying to solve problems. They're trying to preserve whatever problem is most plausibly the fault of the other party.
We need new political platforms focused on consensus-based policies. Not distinguishing our groups from "the other"
Go look at the film industry, and the Writers / Directors / Screen Actors Guilds. The WGA doesn't stop screenwriters from negotiating their own terms. Do you think someone like JJ Abrams is getting paid the WGA set fees? That Tom Cruise works SAG and Equity rates? Of course not.
The point of the guilds in these industries is to set minimum standards for pay and benefits. It is designed to stop studios from exploiting people desperate to work in the industry. I majored in film and many of my classmates have gone on to work in Hollywood - I don't know anyone of them who would say their unions aren't a good thing.
Would you say that it works?
My understanding is that these unions make it more difficult for new people "desperate to work in the industry" to actually break into the industry.
