Point 1 may be a goal of the dutch Tax Administration but all those exceptions and subsidies (toeslagen) are mandated by politics so there is only so much they can do about it. In fact the dutch tax system is actually hugely complicated by the sheer amount of interdependent exceptions and subsidies. So I'm really surprised they use the Netherlands as example.
