We believe we demonstrate how a for-profit company can exercise capitalism to the benefit of people and the environment. We think that the profits of honest work, ingenuity and sweat equity can be shared equally; that workers can be owners without having to be entrepreneurs; that the gap in pay between the highest and lowest paid employee needn’t be a chasm; that health care costs shouldn’t interfere with providing health care and that, though our hair may turn gray as we approach retirement age, it needn’t be from anxiety about how to afford retirement.
