You want to know how your dollars are spent when you buy stuff? It’s not for the wages of the workers who serve you:

Retail workers in New York City earn a median of $9.50 an hour, most are part-time or temporary, and just 3 in 10 receive health insurance through their jobs, according to a new study of the city’s larger retailers.

The study, based on interviews with nonunion workers and released on Monday, largely found poverty wages and highly unstable schedules for the city’s retail employees, with less than a fifth having a set schedule each work week. The study said many workers had a hard time planning for, say, child care or classes because more than half learned their schedules a week or less before a work week would begin.

And you wonder why there are some folks who are surprised by the rise in poverty in America. Duh.
