I haven't seen too many people talking about the 'total' taxes that an entrepreneur generates with his/her business.  eg.  A small business with 10 full time employees, with salaries ranging from $30,000 to $100,000/year generates  large amounts of income tax, employee health taxes, payroll deductions, not to mention HST, and Corp taxes.  These taxes are generated on the backs of the entrepreneurs who RISK everything, (houses, life savings etc) and battle day to day, week to week, year to year with the ever changing challenging business environment.  I know in my personal situation, lean months are met with me sacrificing my salary in order to pay all my employees first and still manage to hopefully break even, so the bank won't want to cancel my operating line.  
One small business that closes up will have exponential consequences.  Sometimes I wonder why I even bother.  Maybe I should just get a nice government job and income split my comfy pension.
