Obviously negative gearing and capital gains tax concessions have to go. I think gone completely, all at once is probably not the right move but I'll let the modelling people figure that out.
That said, using interest rates as a way to throttle economic activity is fucking bullshit.
With the eye watering interest rates we've had over the last several years it's been Gen X and under doing the heavy lifting while as usual boomers enjoy the benefits.
I don't really have a solution but fuck me there has to be a better way.
