Income inequality and wage stagnation finally took their place among the principal moral issues of our time.

When families can afford the basics, they can reinvest in their communities, and higher wages means a broader consumer base for businesses.

People decide what markets should do - they are not a force of nature.

When workers make more money, they respond by being more productive in their jobs and are less likely to leave, reducing turnover costs. This puts money in business' pockets, and workers also then have more money to spend in the local economy.

The minimum wage isn't earned only by people working at fast food restaurants and in service industry work - the average income for positions like nursing assistants, preschool teachers and paramedics are all under $15.

Businesses generally deal with minimum wage increases by finding efficiencies in their business practices or slightly increasing prices if they have to, not cutting jobs. Of course: because they need staff to make their businesses run!

Today, the gap between productivity and compensation for the typical worker is larger than at any time since World War II.
