Elections cost obscene amounts of money; they have always been the domain of the wealthy.
Today, with declining party membership, this means politicians must be either rich or seek large corporate donations to fund campaigns. And corporations don’t give their money away from a sense of democratic duty – they buy influence. When not giving money directly to politicians many corporations are financing the swarm of lobbyists buzzing around parliaments and congress.
But there is an alternative, we can demand a real democracy, a democracy using sortition.
