Right to Work Laws contributing to Vanishing Middle Class and wealth inequality worsening

Much has been made about the shrinking middle class in the United States where the wealthiest 160,000 families own as much as the poorest 145 million families.  Income inequality is the gap in how much individuals earn from the work they do and the investments they make. Wealth inequality measures the difference in how much money and other assets individuals have accumulated. One of the contributing causes of wealth inequality is the labor movement’s diminished economic and political clout, as seen in the movement by states to enact right-to-work laws.
Thanks to collective bargaining, union members have higher wages and better benefits.  In addition, union membership actually raises living and working standards for all working men and women, union and non-union. When union membership rates are high, so is the share of income that goes to the middle class. When those rates fall, income inequality grows and the middle class shrinks.
Corporations did not all of a sudden give workers two days off each week, which we now call weekends, or paid vacations and sick leave, or rights at the workplace, or pensions, or overtime pay.  Virtually all the benefits we have at work, whether in the public or private sector, are because unions fought hard and long against big business who did everything they could to prevent giving us these rights.
Labor membership is shrinking.
