This makes no sense. Why wouldn't you be able to figure out how much others are making? There's plenty of data you can gather, online and from talking to people. Just because data is not public doesn't mean no one is willing to share how much they're making.
If I'm making $50k, and I tell a new company I want $100k at a new job, there is no way that will fly if they know you're making $50k. But with opacity on salary, proper arguments and decent negotiating skills that is definitely achievable.
One example: as a consultant, I have (in the past) easily doubled and/or tripled my rate at times, just based on the setting and by negotiating well. That would never work if everything was public. And in the end, the client was extremely happy with the result + I was happy with the (way above average) increased rate.
>> Norway's tax rate is on par with other Nordic countries: high but nothing exceptional, and you get plenty of benefits (basically you get what you paid for). It's not stopping anybody from trying to make it. As a matter of fact they have one of the highest rate of millionaires per inhabitant (close to 200k for 5M).
Perhaps. But that's also because of the problematic real estate bubble in Norway and Oslo. In a country where everything is highly taxed, certain asset classes (in this case real estate) get distorted if they are taxed lower.
Add to that the reserves in their sovereign wealth fund, and you end up with many millionaires.
There's a reason why Tesla was selling a ton of cars in Denmark, and sales plummeted (down from a few hundred to 6 of 8 cars in 6 months?) when they got rid of the tax credit.
Benefits and healthcare are great and important -- I'm not saying you need super low taxes. What I'm saying is, if you don't specifically need to be in Norway to build out your business, e.g. it's something internet based, there are better countries to base yourself.
Norway is a great country to visit though. I (personally) just couldn't live there, because I don't think the model of such a society would work for me. It's great to be able to have a bottle of wine with friends in a restaurant, without having to pay €300 for your meal + drinks in an average restaurant.
