In general, I would like to see them rely less on market incentives to try to nudge behaviour. That doesn't really work very well. Specifically, I would love to see the parental benefits change. It's very simple. It doesn't cost that much and it would make a huge gender difference.
Also, I would like to see more investment in public housing, in truly affordable not-for-profit housing, so that the percentage of the market where people are paying too much for groceries, paying too much for rent, paying too much for everything and are not seeing their wages increase sees some relief. There is no profit to be made there; you just can't. A profit-seeking company simply cannot provide it at a level that's affordable for that segment of people.
Since housing is a human right and since having that housing security will allow you to increase your productivity in the labour market, go back to school or things like that, I think that's a really important long-term change.
