One thing we should remember is that developers != landlords; there are some that are integrated, but many just build, sell, and move on. Regardless, with the hollowing out of government capacity, I don't think you're going to get any new buildings sans a developer anytime soon. The overall idea is to make the rules for building easier, so that building isn't restricted to your megadeveloper.
Second, the argument was never about "high-end" development only. You're conflating issues. There are two things: 1) many developers today only focus on the higher end, because piecemeal rules and development means that only high-end places pencil out for making any money; they're not going to build at a loss, and 2) major metro areas often have people that can afford market rate in the first place - housing has a filtering effect - people with greater means move into the newer places with more amenities, leaving older, naturally affordable units for others (after all, people can really only live in one home).
