At one time, businesses did use the money for just that, Howlett writes. "From 1960 until the early 1990s, corporations invested almost every penny of their after-tax cash flow back into the business.
"But the tax cuts appear to have reversed decades of tradition. Investment in equipment and machinery has fallen to 5.5 per cent in 2010 as a share of Canada’s total economic output from 6.8 per cent in 2005 and 7.7 per cent in 2000."
Why? I'd say greed, as well as a perception that business can get whatever it wants from governments like Stephen Harper's.
