Anecdata from myself here but I've recently hit top tax in Denmark. I'm ambitious but have started to feel like it's just not worth it scrabbling for an extra 2 or 3k a month when most of it disappears down the end of a hoover. I don't even know how millionaires who can afford their incredible estates in the countryside do it. My first thought was tax havens but I don't know if that's true. It seems like the entire system is set up to disembowel such ambitions.
