Exactly; increasing the GST would be downright regressive, harming the most vulnerable and will fail to stimulate the economy in any way, shape or form.

Doing so just to pass a tax cut for high-income earners will just further exacerbate the wealth divide we are currently experiencing; wealthy people need to be taxed more, not less - to cover our budgetary deficits, broaden our safety nets and invest in public infrastructure like housing, renewable energy, and faster public transport.

Giving those that have enough even more, is just going to have them park those funds in property, rent-seeking and extracting more wealth from the under-class.

It is so counter-intuitive, I can only think that this was proposed by someone with a fetish for public self-destruction.
