The Swedes have had a number of popular tax revolts in living memory. The big one was back in 1979 (about the same time Americans and Brits were having their own tax revolt) when they threw out the socialist government and brought in a bunch of neoliberal reformers.
Until fairly recently, Sweden has been undergoing the same set of neoliberal policies common to western nations. But thanks to being a relatively small economy with an outsized O&G export market, they’ve skated by what industrial centers in the American Midwest and agg sectors in France and the UK have suffered.
Sweden isn’t a high-tax state, its a petro-state with the appearance of high taxes.
