Another idea from Portland, Oregon. Charge higher B&O taxes to companies that pay their CEOs over 100 times the median pay of their workers.
Some business groups, like Portland Business Alliance, don't like the idea and propose, instead, the commonly suggested solution of economic growth; like rising tide raises all boats. Problem is, in my opinion, that's the solution which has been tried all along for years. Income inequality is getting worse. How much overall economic growth do we need? Maybe it's time to try some other strategies.
