While balance can be good some times, the idea that a group of business interests and oligarchs coming together for the sole purpose of lowering their tax bills and buying the nations assets for peanuts, maskerading as a political party, could provide said balance is a strange one.
On the other hand even trying to level everyone to the lowest level is wrong.
Conserving the established power and wealth as well as keeping everyone else down is the only thing they look to conservatives look to conserve. The rest is the lies they tell, in order to get in to do it.
True, the correct balance would be conserve the power and let everyone else to rise, but I undestand it is an utopian vision (the established power would never allow it).
But in the end I think that the main problem is that both parts lost the contact with the normal people but the conservatives are now starting to talk to them again while the progressives are still talking only to themself in an ivory tower.
