The Economic Policy Institute is a left-of-liberal think tank that publishes The State of Working America, now in its 12th edition. This 500 page, incredibly well documented tome contains a mass of information on income, wages, jobs, mobility, wealth and poverty, along with tables, charts and graphs, essentially making the argument that for the last few decades income inequality has increased, wages for working Americans have gone down, jobs have been decimated or converted to low-paying service employment, social mobility for those in the middle and lower classes has rigidified, and “the rich have gotten richer and the poor have gotten poorer,” to quote an old phrase.
The EPI also makes policy recommendations: support workers rights and union organizing, increase the minimum wage, fight against “free trade” agreements like NAFTA, increase spending on the social safety net, etc. The EPI in general and The State of Working America in particular, provide all the factual ammunition you’ll need to fight and win your arguments against your conservative, moderate, or even liberal friends, not to mention make the case for building a democratic socialist United States.
