The fast-food industry is notorious for employing millions of Americans at poverty wages.

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.

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

Annual earnings in the fast-food industry are well below the income needed for self-sufficiency, and fast-food industry jobs are also much less likely than other jobs to provide health benefits.

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

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

We've created more wealth in the past 30 years than the rest of human of human history combined. But half of Americans make less than $17 an hour.
