Actually it's harder not to live paycheck to paycheck here in Sweden, mainly for three reasons;
1) Our wages are taxed to hell and back. While it's, if I remember correctly, like 15-18% in the U.S, it starts at like 20-22% and progressively gets higher the more you earn.
2) A uni degree doesn't actually make you earn that much more than people without one, unless you become a doctor, lawyer and such. Most uni degrees will net you jobs that "only" gives you around 30-35k SEK pre-taxes. As a reference I don't have a uni degree and I earn 30k. The average salary in Sweden is 24k, according to
https://buffert.se/loner-i-sverige/. This has been heavily criticised, as many don't see any point in getting a uni degree, as there's not much more money gained from it.
3) Everything else is taxed to hell and back. 25% is the norm for non-food stuff, 12% for food.
