Headwinds that are starting to assail deep structural flaws in the US and global economies form the basis for my 2017 economic forecast, which looks like an all-out economic crisis building throughout the world. Some of these headwinds are global; some more locally focused within the United States, but that which brings down the US economy wounds the world anyway. Ultimately, global concerns threaten the US, and US concerns threaten the globe. We’re all in this together, even as we seem to be flying apart in political whirlwinds everywhere and fracturing national alliances all over the world.
