In a plutonomy there is no such animal as 'the U.S. consumer' or 'the UK consumer', or indeed the 'Russian consumer'. There are rich consumers, few in number, but disproportionate in the gigantic slice of income and consumption they take. There are the rest, the "non-rich", the multitudinous many, but only accounting for surprisingly small bites of the national pie.
The real threat facing the super-elite, at home and abroad, isn’t modestly higher taxes, but rather the possibility that inchoate public rage could cohere into a more concrete populist agenda—that, for instance, middle-class Americans could conclude that the world economy isn’t working for them and decide that protectionism or truly punitive taxation is preferable to incremental measures such as the eventual repeal of the upper-bracket Bush tax cuts.
