I think you have been spoiled by the Schengenregelverket
Ask your mom and dad about how people used to travel in Europe in the 70s, the procedures involved with getting work visas etc.
The USA is not part of the Schengenregelverket and has some strict (some would argue not strict enough) rules about who comes in, for how long, and whether they are allowed to work (professional sports are considered a form of employment). Be happy that as a Swede, you can enter the USA for tourist purposes without a Visa.
Despite being a full member of the EU, a US ally in Iraq, a member of NATO, despite getting through the economic crisis better than many Western European countries, my Polish relatives cannot visit my parents in California without first dealing with a lot of red tape to get a tourist Visa.
Your friend was careless last year. This year he will suffer the consequences. Redirect your anger, dude.
We have to get visa too even for 3 months.Redirect your anger, dude? Like my relatives had to flee from polen to US because they had crooked noses just before WW2? They had probably Visatrouble. And a portion of anger maybe? And i can't ask my father since i couldn't find him in the states while he was alive. But that's a totally different story.
