Income tax 'cuts' almost always increase the structural deficit.

Income tax 'cuts' almost always increase the structural deficit.This is because the commensurate cut in spending is never done.
Reagan and Bush and now Trump have done this in the USA. Howard did this in Australia ) It should be remembered the ALP did not criticise this. Indeed they implemented some of the cuts.
HERE is a good article about what a structural deficit is and what it means. HERE is my modest article on it. HERE is a good article about a person who does not have a clue about the subject!

If a Government cuts taxes but not spending it means revenue will not rise as it should.For a government to do this in the context of budget repair it is the height of fiscal irresponsibility. More so if you put a cap on revenue as a % of GDP.

Me thinks if the ALP puts budget repair top of the pile and not tax cuts they will romp in.
