> Want to reduce the influence of landlords? Let more people build multifamily housing. Who's keeping that from happening? It's not the landlords. It's the people who live in freestanding single-family housing.

A lot of landlords live in freestanding single-family housing. Your description of every landlord you've ever met is quite at odds with my own. I know very few landlords who live in their properties. They have a nice big house for themselves and rent out apartments or additional houses.
