From a skim, I see nothing about wealthier homeowners having broader political influence - to systematically (vs. one-off) encourage such less-than-fair assessments, and discourage reform. Similarly, nothing about the incentives for residents (voters) in an area to use regressive property taxes as a poll tax - whether trying to prevent the less-well-to-do from living there, or to gear up gentrification for their individual benefit (higher real estate value).
