He's probably making fuck-all off of the merch. My suspicion is that Caden's basically treating him as a cash lolcow with which to pay off the property and buy drugs, in part by way of the tugboat and in part by working him like a kid in a Chinese shoe factory through making trinkets. That's not to say that he has no income whatsoever, but rather that he keeps relatively little of what he has or receives.
I believe this to be the case too. It's either an "old mining town" scenario where most of CWC's merch sales revenue goes straight back into Caden's pocket as payment for room and board, or (a bit less likely) a "child star" one where Caden or someone else from his camp tells Chris "we're taking care of your finances, but in the meantime, you want that Lego set or w/e? We'll get that for you" without any actual money ever passing through CWC's hands.
Especially when shopping malls have been a dying trend for decades now.
Chris is essentially a shopping mall, he was born in the 80s peaked from the 90s to the 2000s but as the 2010s rolled around people lost interest. He stopped being worth the effort and now only a few stragglers still drop in the see the decay before their very eyes.
Shopping mall mass death is pretty much a North American phenomenon. Sure they're not exactly in their prime in the rest of the Western world, but they're having some very dignified twilight years, so to speak. Your average suburban English mall still looks like a backdrop from a 2000s teen sitcom on any given weekend.
That's not Shengen, that's EU freedom of movement. Ireland is not Shengen but if you're an EU citizen you have the right to live/work there(indefinitely). Conversely, if you have a Shengen visa as a non-EU citizen you may only travel to member states as a tourist for a limited time.
This one's tricky. EEA ≠ EU ≠ Schengen area (which includes EEA countries but not the whole of the EU).
If you're an EEA citizen (this is EU plus Switzerland, Norway, and Iceland), it's like you said.
If you're a visitor from abroad, you can travel freely (without passing through customs or border control, that is)
only within the Schengen area.
If you have a residence permit from an EU member state, you can freely travel within Schengen, but unlike EEA citizens, you only have the right to live and work in the country that issued your visa, even if your partner is an EEA citizen.
Not that either of those caveats would be of any concern to Chris, even if he gets to legally marry egg and somehow manages not to scare or piss her off for long enough to actually get Finnish citizenship through her.
