>The massive downzoning of the 1980s...

To put numbers to this for those who aren't aware, LA was zoned for roughly 10 million people in the 1960s and by the 1980s it was zoned for roughly 4 million. It's part of the reason the city has had population growth slow to a crawl. It was decided some 40 plus years ago that LA should stay under 4 million people, so it has even til today. But the number of people who want to live in LA is constantly growing, so housing prices continue to rise and as a result lower income people are slowly but surely being pushed out of their homes and out of the city entirely.
