But for the Brits stuck or have only left in the past 10 yrs, they are fucked, well and truly, as for farmers or land holders (my family are) they will basically loose most of those assets to the state as the 20% tax is on a fixed asset that doesn't produce such a year or over its time basically you become a maintenance crew for lousy income and lousy work life balance but it is a responsibility.
In my families case over 500 yrs history and a Royal Charter from King George III about to end, our watch is over i guess (RiP), fitting actually father is retirement age, grandfather was still involved into his late 90's, i am not interested due to tax on wealth generated overseas so it's basically a excuse to hand it to the state in my family - consensus.
