It depends, since all states manage their taxes differently. Usually it’s done via determining ties from the foreign resident to the state in question (e.g. is the resident receiving mail, operating a business, or residing x days of the year in the state?), and taxing on that accordingly. My state doesn’t collect income taxes, so I’m not well suited to speak on this topic.
The taxation part of this is a bit of an unfair point. The US allows for an exclusion of ~$150k in foreign earned income if the US citizen qualifies as a bonafide resident of a foreign nation. On top of that, the IRS lets you deduct any taxes paid to a foreign government dollar for dollar against owed US taxes, and since most other developed nations have a higher tax rate, this essentially wipes out your US tax obligations (federal only, some states will still apply taxes separately). The only people actually double paying taxes are the ultra rich, but they obviously don’t pay taxes at all since that’s for the poors
Obviously, the system is still stupid and overly complicated (why should I even file a return with the IRS when I don’t owe anything?), but it’s not as egregious as this video makes it out to be
Completely unrelated to OP, but I just discovered this and I feel a need to broadcast it from the rooftops:
If you play any jam music or find yourself needing chord or lead charts constantly, then you should absolutely get iReal Pro. It’s pricey for an app, and I have no idea if the creators are ethical people or not, but the product is incredible: https://www.irealpro.com/
This has been such a game changer for playing with new people or jamming on tunes
Ah this happened to me this weekend! Not the train explosion, but the winedbg flood. For me, it was because I had my proton and steam Linux runtime installations on an NTFS disk instead of something more Linux native.
