There goes civilisation...

The money could come from somewhere else (e.g. diverted from funding wars - simplistic, but true).

Also, these bankers that are leaving have had UK tax spent on them as much as any other resident that lives in a community where the streets are cleaned, emergency services are ready for action, and so on. So them going lessens the tax burden.

Going back to something pj(pj) said, there are more important jobs that need doing. Imagine if all cleaners downed tools tomorrow...

Yeah, but all the bankers leaving have paid a lot more in taxes than most of us will ever earn in a year. When you net the amounts, I'm pretty certain they'll come out in the positive. Especially since they all think the NHS is crap and prefer to use private health care or go back to France for medical treatment.

Well if I lose my job because of those idiot fixed income monkeys, I'll swing by your street and give it a good clean. Oh wait no I can't. The council probably won't give me a work permit. Damn.
