Bill Morneau continues to describe these as "loopholes" (defn.: "an ambiguity or omission in the text through which the intent of a statute, contract, or obligation may be evaded").  In fact, he's referring to deliberate government policy that small business owners were encouraged to pursue.  Moreover, and most importantly, these rules provide no after-tax advantages to individuals.  Market forces would quickly erode any such riskless advantage.  As an example, imagine plumbers suddenly paid no tax - would plumbers be wealthier in the long run.  No.  More plumbers would enter the market, driving down prices (to the good of consumers) and profits, until plumbers earned exactly as much  as they originally did relative to other professions.  The only difference is that we'd have more plumbers.  Suddenly charging those plumbers an "equivalent" tax rate would amount to a dramatic reduction in their fair wage.  That's the reason these tax changes are fundamentally unjust.
