Not everyone in the capital of the country where Thomas Piketty lives is happy. Lobby group 40 Millions d’Automobilistes believes raising SUV parking fees is the work of an ‘ultra-urban (sic) and anti-car minority’. The fact that paying a sort of ‘sin tax’ should not be a problem for rich SUV-owning Parisians is apparent. But the French have a history of this sort of thing. Post-revolutionary France imposed a tax on wigs. Like SUVs, wigs were worn as a mark of HNI-ess and social status. Wig-wearers, though, made the higher tax into a show of wealth, happy to pay extra so as to signal to fellow Parisians without elaborate headgear that they were rich. The same approach could apply to SUV-owners. Flaunt your parking tickets to show you’re loaded.
