LOL that is total bullshit. In SF, they oppose high-density high-income housing too. It's total motte and bailey shit. Here's the real algorithm:

    if density == low:
      return "This won't solve the problem"

    if income == low:
      return "This ruins the neighbourhood character"
    
    if density == mid and income == high:
      return "This is gentrification and soulless coffee shops!"

    if density == high and income == high:
      return "This is for Arab/Chinese/local-xenophobe-target-du-jour investors only"

    return "This ruins the neighbourhood character"

The absolute bullshittery around this nonsense is really something.
