It is not that simple. While the country is rich and getting richer, it's population is getting relatively poorer. Housing is at an all-time high (as it is in so many places in the so called developed world). More and more complain about food prices, especially fresh vegetables and for some reason, chocolate. The country is completely dependent on imports.
They restricted the budget allowed to communes, which not only stopped their planned investments, but had to cut several services such as school and culture programs, mostly in the less dense areas.
Add to that the relatively weak krone, and you get a very strong feeling of moving down. This pushes their local populist right wing party (FrP) high.
Many would not understand the remote support while they experience those cuts.
Not negating the price hike, but for whatever reason I don't see people from other countries complaining about chocolate so specifically. In France for example, housing, fuel and electricity are big topics, but chocolate is not.
