Wealth inequality is becoming a tense social issue with executives paid 185 times more than their average employee. This coupled with the stagnation of middle class wages and bonuses being handed out in times of financial crisis is creating resent for the 1% that holds 40% of the wealth in the nation.
Growing resentment is bad for business. Social unrest will eventually affect your bottom line with more and more people boycotting and choosing to take their business elsewhere. Making a pledge to take a pay cut willingly is a big PR win that says you are not part of the problem, but part of the solution.
Your pledge could create new jobs and raise wages at your own company. A well paid workforce produces more. Less unemployment allows people to keep consuming products. This is not charity or a handout, you are investing in the well being of the nation which just makes sense for all of us.
