if only parties tackled the tax system by simplifying and tightening it by complete reform and more taxes on assets than income. Then we could see a shift in who holds the wealth. Unrealistic due to both politicians and electorate demands. Parliamentary democracy doesn't offer either.
Though I've not watched it yet, Natalie often impresses me. I don't think her performance on DP is reflective of the party. Read their policies on their site are reasonable enough. Especially defence.
