Higher taxation to rich doesn't hurt them or stop them from making money.
Still one of wealth tax might be massively problematic to implement. How do you value wealth? Stocks? If people taxed don't have cash on hand they are forced to sell some and if this is wide practise it will affect the markets...
All in all it's structural issue and there is no simple easy solutions in long term...
This idea of a 'one time tax' has been being floated by monetary authorities for a few years as a way to solve the debt problem - it's not just Britain. And that it's a dumb idea doesn't mean they won't do it. They've said they'd do things like the Cyprus haircut again, and they will.
It's not about what's good for you, but what's good for them. You are just tax-cattle.
And every single time the rhetoric about "sock it to the filty rich" starts up, the ones that get slaughtered are the middle class, because that's where the bulk of the takables is.

My grandfather died in 1989 having spent his entire working life at the coal mine. He was such a hard worker his nickname was "the Iron Man" (nothing to do with Stalin BTW). He was an intelligent man who could discuss with you articulately any subject you wished to raise - and this when the dissemination of information via the internet was but a dream.
In his will he left £1k for each of his children (he had 5) and £100 for each of his grandchildren (he had 8 ) - he lived in council accomodation so had no property to call his own.
Whats £5800 in todays money ?
5800 that was wasted, by the government not having scarfed it up. In the eyes of those who want to take everything they can.
