The rich are getting richer. The top 5 percent of earners in the U.S. accounted for nearly 40 percent of personal consumption expenditures in 2012, according to the Institute for New Economic Thinking. That is up from 28 percent in 1995.

The percentage of Missouri workers who are members of a union dropped to less than 9 percent in 2012, following two years of slight gains.

The federal Bureau of Labor Statistics released its report on Monday. It showed that 51,000 fewer Missouri workers were in a union in 2012 than 2011. The state was part of a larger national trend, but that 2 percent drop was among the largest.
