Manufacturers across the nation celebrated National Manufacturing Day on Friday and the topic on many people's minds was reshoring. Earlier this week, General Motors announced it will build a software development center in Michigan, joining a number of companies like Google, Caterpillar, GE and Ford who all have revealed plans to make products in the U.S. previously outsourced or purchased overseas. Although the prospect of a reshoring trend and resurgence in U.S. manufacturing has been a topic of debate, there are still skeptics who say the evidence of this movement is highly anecdotal and the U.S. still faces a future of offshoring.
