UK is not only for middle eastern and russians. Last I checked UK was the favourite destination for french tax exiles (as well as entrepreneurs), ahead of Belgium and Switzerland. Other wealthy western europeans and asians must be moving there, also there is a rather straightforward investor immigration scheme open to non EU citizens in UK, but a single million won't cut it.
The richest frenchman Arnault moved to Belgium! Also the whole family Mulliez from Auchan live in Belgium. Rich french families move in groups to Belgium. So they don't go to the UK.

Can't dodge Uncle Sam till you gain ex-pat status IE legal resident of a foreign country for 10 years or more....
An alternative to Monaco is Zug in Switzerland. Suggest trading via a Zug company, tax max 15% net. Personal tax max 22%. Cost of living in Zug lower than Monaco and living quality much better. Rents in Zug 40% lower. Monaco is a loud and stinky place bearable only on weekends. Lots of young and middle age expats and international people in Zug, easy to get into contact with. Monaco mainly older folks. Contacts with other traders via meetup.com and internations.org. Traders with family and kids much better off in Zug. (Note: I posted this in another thread.)
