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

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

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

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.

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

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!

Most fast-food workers can't easily join a union, because they don't work directly for their parent company, such as McDonald's or Subway. Instead, they work for individual franchise owners, ensuring that each individual fast-food outlet would have to organize and win union recognition separately. So there's not one central employer to bargain with, as in a traditional union campaign.
