We the people
Lawrence Lessig, a lawyer who did some deep thinking on the internet ansd copyright reform, has been lookiing deeply at the problem of corruption in democracies. Though he is focussed on the US system, we can see similar problems in election financing in Australia: consider the recent problems with fundraising in the NSW Liberal party, who were trying their best to not declare political contributions by big corporations.
Perhaps we need to campaign for public funding of all candidates in elections here? Or at the very least, uniform, effective disclosure of election funding across state and commonwealth elections?
