why haven’t…

Probably because there’s been plenty of other things to pork barrel on.

The problem with your hypothesis is that these parties just go ahead and do costly things without waiting for the electorate anyway.

that’s subjective

No it isn’t, they’re better by every metric and if you don’t know who I’m talking about…I don’t know what to say to you. Furthermore, they stand up for us and the disadvantaged, whereas Labor are happy to let American tech companies kick people off the NDIS to fund submarines sold by pedophiles. Or let gas companies take our resources for nothing. Or let gambling companies advertise to whomever they like.

this might shock you

This chestnut again. Labor relies on the Greens and independents to pass pretty much anything decent and when they want to default to cruelty, they need the Coalition. They’re not too bad at stealing minor party policies either…the Greens have argued for state funded dental for years plus the reversal of CGT and negative gearing on housing.

Labor’s had no interest in these until it’s politically expedient, and used one to cover their cowardice in selling out the nations sovereignty and cruelty. Which btw they teamed up with ON and the Coalition to do on both occasions. All three, if we include gambling ads.

form government

I thought they did that with Rudd/Gillard

implement them

Which Labor, for all its power, can’t do without Green or Coalition help either. We notice where Labor runs when they want to kick down.
