There is so much BS propaganda in that article.
Indeed. Bloomberg is a brilliant guy, but he definitely has an agenda he's pushing.
The main reason corporations are sitting on cash, is uncertainty (or hopes for a better regulatory and tax environment around the corner).
You want to see corporations investing, hiring and growing the economy? Rip up the entire current IRC, and replace it with a VAT along with any transfer of ownership, be it by sale, gift or inheritance, become a taxable event (and add some cross-border provisions just to discourage off-shore schemes).
And as far as the missing parts of education and infrastructure, I couldn't agree more that those are essential pieces in order to grow the economy, but obviously the old recipes don't work, so we need to try something else in order to fix those problems.
