The CEO of the insurance company Aetna predicts that 2015 will be the year that wages for the lowest paid workers in the country will finally begin inching up, citing moves already made by companies like McDonald's and Wal-Mart as the first of many, according to the Wall Street Journal. Over the next six months, he said people will see more and more large companies come out with "wage increases that matter," versus in the past few years where average wage growth was about 2 percent. While he noted that such a change could cost his own company $26 million annually, though also said that the company could save money from reduced turnover.
