Bad move there. You should've put all your savings in another account and them showed your regular statement. That's what I did. I pay my taxes and I'm not losing all my savings becuase the economy is shit.
Having paid your taxes doesn't make you exempt from the same rules that everybody else has to abide by though. A line has to be drawn at some point, and realistically, a person without significant savings *needs* help a lot more than someone who does have those savings.
If you want to know exactly how the whole thing is calculated (you might be surprised to know it's not just a random thing that THE MAN decides based on how much he hates you), it's all publicly available here.
And before you do it, I'm going to say please don't bring up 'oh but they probably just spent it all on cigarettes and drinks' because neither you or the government has the ability or right to make moral judgement calls to determine eligibility.
