The government continues to spend beyond its income, so this deficit is money that is being borrowed from banks and money markets (obviously not on a credit card).

Just because you are happy with the unfairness of the current system, does not mean that there should not be a referendum. The majority of voters at the general election voted for parties that wanted to have a referendum on electoral reform (Labour, Lib Dems, Greens, SNP, etc). In fact the Labour Party manifesto was closest to what has actually happened, and I believe this is the manifesto that Roz supported at the last general election.
