Jobs are taxed equally, but the people who earn more also contribute more. There is no shame in that, it allows most Europeans to actually live in a society worth contributing to.
It's easy being happy about the taxation regime when you do 35 hours a week. It's not uncommon for a doctor to do closer to 60h and up to 70h.
And quality of life isn't even that great. Crumbling infrastructure, long wait for public hospitals, dirty streets etc.
The US has in some ways a fascinating culture. People there, especially in the middle class, can be driven and open in ways that are usually outside of the imagination of even middle-class eighteen-year-olds in Europe, well-educated or traveled though they may be. But in America some of them start out having already lost, and they know it, and they truly in their hearts believe it's their fault. And it's heartbreaking.
I paid taxes in the US, you know? And it was the worst. Because I was still paying those 20% or whatever it really was, but I couldn't see where they were going. It could have been the court system I guess. Every other block had some kind of sign with something prohibited and "violators will be prosecuted" written on it. The roads were nice.
I don't "do" 35 hours per week, so I'm not sure where you are going with this.
The last bit is (almost) laughably wrong and tells me you have no idea what you're talking about. Even if that was all true, the US has tent cities of vagrants that keep being kicked to another city to be their problem, people that freeze to death in the streets with literally nowhere to go. Let me wait 6 months or however long it is in your fantasy universe. Anything to prevent contributing to a society that treats people like the worst of the meat industry treats it's cattle.
