It's supporting taxpayers funding both sides in the Child Poverty Inaction Group case.
Pita Sharples has the audacity to say "Of course, I believe every taxpayer in this land would prefer that this case hadn’t needed to come to court, to involve the international experts and the expenses that no doubt the Crown will incur in presenting their defence". Indeed, had the taxpayer not funded the socialist CPAG, it wouldn't. Furthermore if Working for Families is abolished (as Lindsay Mitchell rightfully advocates) and the proceeds used to cut taxes, then there wouldn't be any case, and then there would be no discrimination - except of course the tax system.
You see for some reason (if I was in NZ, but it applies also in the UK), when I earn an extra dollar I lose 39c of it, but when most people do, they lose only 15c or 19.5c, some lose 33c. It's quite discriminatory, and I don't impose any greater cost on taxpayers, I don't live an unhealthy lifestyle, I don't have children, I don't interact with the criminal justice system, I don't own share in any businesses that receive subsidies. Yet I would pay a lot more than those who DO have a lot of children, who are beneficiaries, who interact with the criminal justice system (or whose kids do), and who live unhealthy lifestyles, and depend on others to pay for their housing.
