In 2018, the SF median household income was $97k [1], which suggests a median individual income of about $76k [2]. An average private-sector employee receives benefits worth 42% of their wages/salary [3]. So a hypothetical median SF worker earning $76k in salary would receive about $32k in benefits, for about $108k total.
So it seems to me that the "pooper scoopers" combined salary+benefits of $184k really is, in fact, extraordinarily high.
