Democratic presidential candidate Bernie Sanders announced Monday an “income inequality” plan calling for steep tax increases on companies that pay CEOs far more than their workers’ median salaries. The Vermont senator’s proposal would raise taxes 0.5 percentage points on companies paying top executives more than 50 times the median salaries of workers. Tax penalties would rise from there, up to a maximum of 5 percentage points for firms whose highest-paid official earns 500-plus times median worker pay.
