I get that starting a business is a risky venture and needs to be rewarded, however the evidence is in that the current tax laws are a way for many people with the means to avoid paying what they would otherwise have to on a level playing field.   

Is it fair that a salaried doctor making $200k a year pays the same tax as an incorporated doctor that makes $350k a year and either pays his non-working wife and kids?  Or a business man that owns a real estate company and after paying the wife and kids also leaves an additional $200k a year in the corporation name but invests in stocks etc. and generates strong returns that he then pays only half the tax the rest of the people do on similar investments.   It is a loop hole that must be closed to level the playing field. 

Corporate taxes are already low to encourage business and hiring and investment (in the corp) not as a way to cheat the tax man.   Let's never forget in the eyes of the law a corporation is a legal person.
