Yes, everyone deserves a proper employment contract but that was a misinterpretation of what I was trying to say.
Those who intentionally try to avoid taxes by setting up offshore business is what I am having a go at. Interesting tax planning was a selling point from Brookfield when it was new. They could provide split payment, e.g. 1/3 in UK, 2/3 in Switzerland to keep tax man happy at home. I've met several of these, they're nice enough people, no psychopaths, but I bite my tongue as to what I think about it.
