When we spoke about workplaces in 1972 we mainly were referring to old-line manufacturing firms, on the one hand, and Main St. shops and restaurants, on the other. Both of those categories are now insignificant in terms of employment. Today, the economy is dominated by the rapidly growing Low-Cost Operators - national discount and mall chain stores, fast food franchises and supermarkets - which offer employees low salaries, few benefits and little training.
