"If we, your landlords, own a LOT more housing, surely you can see how that will trickle down to YOU eventually owning a house. It's obvious isn't it? Our goal as investors is to build so many houses that prices will crash and everyone will be able to afford a house to live in. That's what we deeply want for all, and that's why we need to end zoning laws."
There's this weird tendency to treat people in new housing as not people, as non humans.
In reality we have a massive housing shortage, and tons of people living in crowded situations, and massive displacement of the working class out of California.
All those people exist, are real, and are helped massively by new housing. One doesn't have to own a home to be a human with needs.
Why do we have to be thankful and grateful for that?
The landlord lobby explicitly opposes this because new housing challenges their monopoly. They are pro-shortage for very obvious reasons, and this comment shows you have misunderstood the situation entirely.
