Proof can be found in the annual “Public Viewpoint on Manufacturing” survey from Deloitte and The Manufacturing Institute. The survey studies public perceptions on a wide range of manufacturing topics.
Here are a few examples:
90 percent of respondents rated manufacturing as ‘important’ or ‘very important’ for their economic prosperity and America’s standard of living
84 percent either “strongly agree” or “agree” the US “should cultivate a more strategic approach to developing its manufacturing base.”
And 82% support further investment into the U.S. manufacturing industry.
There’s an excellent article summarizing the report in Modern Metals magazine. You can read it here.
