How does current Atlasian law differ from US law on this?
On the issue of quotas, not so much, aside from tangentially related legislation like the public housing bill. Waiting lists for people who qualify are constantly full, with wait times lasting years, potentially, and states resorting to one-off lotteries just to actually shake up the process. Our welfare system in this regard is trapped in a 90s-boom-time philosophy when it wasn't actually required to let more people in, when now, it most definitely is.
