Sawtown Report V5 N2 - Do We Need Unions?

 I was asked if an employer provided everything that a union provides would we still need unions? 

 The first obvious answer is if an employer provided everything that the union does then one would not need unions.  But on further reflection it is clear that even if an employer matched the union wage scale, benefits, and working conditions there are still three reasons why unions would still be needed.
