What's a bit weird is that so many people think that the loosening of zoning regulations - allowing, not requiring developers to build more densely - is the real social engineering. Don't worry, there will still be plenty of single family homes available.
As I've written many times, it would be illegal to build the urban hellhole in the urban hellhole today. There has been a bit of progress in the way the city sees these things, though it's generally two steps forward and one step back.
