I wasn't aware that the UK had a written constitution... thought that was a US thing.
As for bailing out banks, it isn't that simple - it's not just about 'bankers' getting burned at all, which nobody other than they would have minded. Had RBS and HBOS not had intervention applied (and Northern Rock well before 2008), there would have been many thousands - if not millions - of normal depositors on the street, everything lost. You can't let that happen if there's a way out.
The problem isn't bail-outs: the problem is the poor fiscal controls that were, apparently, in place but were not applied because in some cases its the very same people who do both the gambling and the controlling. I repeat again: you should try to get to see the DVD Inside Job, which names names etc. and is an eye-opener as to the enormity of what and why, and also about who the people are in the universities, holding powerful positions relating to fiscal education, yet in their extra-campus rôles as consultants and advisers to government, were often the same dodos pulling everything down... the concept of perpetuation rings alarm bells. And those same players are still in place.
Regarding rights to privacy, the same thing applies to banking offshore. It was never illegal, and there are/were clear(ish) rules about who, where and when one could. Hosts of international law companies and accountants existed to advise. Then, the US leaned on Switzerland and she gave in. That was a mistake. It was the domino effect writ large, with the majority of the rest caving in. Many of those offshore bank branches are now pretty much pointless, and I suppose that it won't be long before most close and the islands turn to deserted ones, just like in the olde tales of the Spanish Main. Except that it'll spread far wider than that geographic zone.
There's a lot of misunderstanding around about offshore. It was never meant as a tax-free banking device: the obligation to post returns/interest etc. to some country or the other was always there, and it's almost impossible not to be either resident or domiciled somewhere.
So well done, Big Bro'; you blow it at home then seek to make amends by screwing everyone else.
