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 free market hasn't done a very good job "figuring out" how to pay workers enough. If it was solely up to the market, the people with the least power would be paid pennies ... or less.

The vast majority (over 80 percent) of fast-food and similar low wage service jobs (<$9.24/hr) are held by adults. A quarter are adults over 40. Another quarter are moms raising kids.

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!

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

Fast food also has a uniquely difficult business structure for workers to achieve better wages and working conditions.

A September 2015 poll found that, by a 3-1 margin, voters are more likely to support political candidates who favor raising the minimum wage.
