As usual, Robert Reich says it better than I could (emphasis added).
“Paid-what-you’re-worth” is a dangerous myth.
…The real difference is the GM worker a half-century ago had a strong union behind him that summoned the collective bargaining power of all autoworkers to get a substantial share of company revenues for its members. And because more than a third of workers across America belonged to a labor union, the bargains those unions struck with employers raised the wages and benefits of non-unionized workers as well. Non-union firms knew they’d be unionized if they didn’t come close to matching the union contracts.
Today’s Walmart workers don’t have a union to negotiate a better deal. They’re on their own. And because fewer than 7 percent of today’s private-sector workers are unionized, non-union employers across America don’t have to match union contracts. This puts unionized firms at a competitive disadvantage. The result has been a race to the bottom.
…The reason Wall Street bankers got fat paychecks plus a total of $26.7 billion in bonuses last year wasn’t because they worked so much harder or were so much more clever or insightful than most other Americans. They cleaned up because they happen to work in institutions — big Wall Street banks — that hold a privileged place in the American political economy.
…The “paid-what-you’re-worth” argument is fundamentally misleading because it ignores power, overlooks institutions, and disregards politics. As such, it lures the unsuspecting into thinking nothing whatever should be done to change what people are paid, because nothing can be done.
It’s not that working Americans are lazy/incompetent. Capitalists are greedy and powerful.
