My city passed a "mansion tax" for people who own multimillion dollar homes. However the threshold for where the extra tax kicks in isn't adjusted for inflation or the top X percentile of most expensive homes. So we're on track for the average single family homeowner to be paying the "mansion tax" in another decade or so. It's already hitting some multifamily buildings. Also reminds me of AMT. When it was originally created, one of the selling points was that it would only impact 155 wealthy families, households who made the then-insane income of over $200k but paid very little in income taxes. By 2017, over 5 million households were paying AMT, particularly those in states with high SALT taxes where $200k/year doesn't afford as lavish of a lifestyle as it used to.
