Housing law bans <i>increasing</i> rent based on number of children. I&#x27;m fairly certain that -at least in SF- it doesn&#x27;t prohibit the <i>reduction</i> of rent for each child present in one&#x27;s family.<p>Why would labor law ban the <i>increase</i> of one&#x27;s salary based on size of one&#x27;s family?
