The idea of a "maximum wage" — a limit on the income that society's richest can pocket — has emerged as a real political issue in the UK, and last year the British publisher Polity asked me to do a title on income maximums for its new "Case for" series.

I've done just that, and The Case for a Maximum Wage will now be appearing this April in the UK and a few months later here in the United States.
