This is an encouraging step, and it's nice to see the heat being turned up on the grocery monopoly.
I think we need cost controls and compulsory transparency about pricing. What stick exactly are the grocery companies wielding to prevent measures like that from being rolled out? A federal government with vision and principles would have had a plan and gotten this done yesterday. Instead, we're waiting for the assent of megacorps to a non-binding code of conduct, which everybody knows is total vaporware.
I can see why people are disaffected by all the hand waving about 'competition'. Increased competition is probably part of the solution to the problem here. But it's not a valid starting point. It's a result of wise policy and good implementation.
