If you look at a demographic pyramid for NZ, there is no "baby boom bulge". So you're arguing a myth. Get over it.
But you're just continually avoiding the obvious point: boomers and the gray generation tend to be singularly focused on preserving their self-interest (and their progeny's ability to continue their unearned advantage through winning the birth lottery) and have exerted an outsized political influence through aligning their interests with the political expedience of the likes of NZF, in the context of NZ. This is easily observable to anyone.... whose eyes are basically open. Boomers and the grey generation have also had the advantage of almost unheard of and highly sustained (but by no means uninterrupted) economic conditions where even frankly the historically "lower" classes like your average shopkeeper or bus driver (and the like) have managed to buy a house, have lifestyles that similarly situated young people today have no hope of repeating, and even in some cases accumulate capital that has grown and provided exponential advantages that young people today have no hope of ever getting near. How's that okay? And why is it unacceptable to call such obvious matters out?
From a pure selfishness POV, my wife and I will benefit from the ongoing favouritism towards holders of capital since we both have well-to-do parents. It's just not a morally acceptable state of affairs in my eyes. Typically the people most keen on blocking any kind of reforms are the boomers and the gray generation.
And if that offends anyone, if we are serious about a genuine debate, the answer should be: tough ****.
