The second key factor: We now have a much better sense of how much maldistributions of income and wealth endanger every aspect of social decency.
Societies that let income and wealth concentrate at the top, research over recent decades has made abundantly clear, don't work particularly well. Inequality distorts our democracy, erodes our economy, and coarsens our culture. Researchers have linked rising inequality to nearly every social malady that afflicts us, from traffic congestion to mental illness.
The third reason why serious people have begun talking maximum wage: We now have a politically plausible path to an income cap. Here in the United States, we've actually started down that path. We've entered the age of a new "pay ratio politics."
This year, for the first time ever, U.S. corporations must disclose the ratio between their CEO pay and the pay of their company's median -- most typical -- worker. Many of us working for a more equal America believe this disclosure could turn out to be a real game changer in the struggle against inequality, the first step toward a maximum-wage America.
Corporate America, on the other hand, has been bellowing "foul" against this ratio disclosure mandate, at times almost implying that disclosure will bring the end of civilization as we know it. In fact, disclosing data on the gaps between corporate execs and what they pay their typical workers will help us become more civilized.
What makes, after all, for civilization? Limits. In civilized societies, we set limits all the time. We limit how fast motorists can drive. We limit how many ducks hunters can shoot. We limit how much noise our neighbors can make. We set limits like these to make our societies better places to live. We set limits because we understand excess -- in anything -- never does us any good.
But we have no limits at all on how rich people can become -- and that's not good for anyone.
What might an appropriate limit on income be? In 1942, Franklin Roosevelt, the President of the United States, had one answer. After paying federal income tax, FDR proposed, no individual American should have an annual income greater than $25,000, about $375,000 in today's dollars.
In effect, FDR was proposing a 100 percent tax rate on income over $25,000.
Congress didn't buy Roosevelt's 100 percent top rate, but Congress did set a top tax rate at 94 percent on income over $200,000, and that top rate would hover around 90 percent for the next 20 years, years that would see the United States become the first mass middle class nation in the history of the world.
But those steeply progressive tax rates in the United States did not last. They could not withstand the fierce political pushback from the rich. The wealthy simply had more of a direct stake in slashing high rates than average Americans had in keeping those high rates in place.
So those top rates fell, to 70 percent in the mid 1960s, to 50 percent in 1982, to 28 percent in 1988, before jumping up a bit. The current top rate: 37 percent, and that's only for paycheck income. On income from investments, America's richest pay taxes at just a base 20 percent rate.
Progressive taxes, as traditionally structured, proved unsustainable in the 20th century. We need a new structure. We need a tax system that gives average Americans a clearer personal stake in keeping tax rates on high incomes high -- and the wealthy a reason to care about those without wealth.
A new tax structure that linked incomes at top and bottom could meet both these goals -- by placing a 100 percent top tax rate on income above a set multiple of the annual income that comes from working at the minimum wage. If we had this linkage in place, our richest and most powerful could only see their incomes increase if the incomes of our weakest and poorest increased first.
Imagine a world with this sort of "maximum wage" in effect. Our most privileged would have a direct personal interest in improving the life chances of our least advantaged.
Those of us already graying will likely never see that world in our lifetimes. But we could move meaningfully in that direction if we began challenging the pay practices now common in our single biggest contemporary contributor to inequality, the modern American corporation.
And this takes us back to that new corporate pay ratio disclosure mandate. By the end of this year, every major U.S. corporation that trades on Wall Street will have made these disclosures. Many already have. At Walmart, we now know, typical employees would have to work 1,188 years to equal the pay that went last year to Walmart's CEO. At McDonald's, typical workers would have to work 3,101 years. At the toymaker Mattel, just under 5,000 years.
What if we placed consequences on the corporations with outrageous ratios like these? What if we subjected corporations with wide ratios to a higher corporate tax rate? Or denied them government contracts and subsidies?
Work toward these ends has already begun. In Oregon, the city of Portland has raised the business tax rate on companies that pay their CEOs over 100 and 250 times typical worker pay. San Francisco has a similar proposal up for a referendum this November. Six states have legislation pending that either ups business taxes on companies with wide ratios or penalizes these companies in the government procurement process. In the UK, the Labour Party is pushing for legislation that would deny government contracts to companies with a CEO-worker pay ratio wider than 20 to one.
If we made pay ratios central to our progressive political project, we wouldn't have to limit ourselves to legislative actions like these. Published corporate pay ratios could inform and inspire grassroots citizen campaigns on a wide variety of fronts.
With pay ratios, almost every social situation would become a potential arena for egalitarian struggle. Students could join with university faculty and staff to demand that their institutions link top administrator salaries to a modest multiple of pay at the base. Donors to nonprofits could insist that the organizations they support limit their executive pay to a similar multiple. Workers could take pay ratio demands to the bargaining table.
Every such grassroots campaign waged would help stitch an awareness of pay ratios into the fabric of everyday life. Every victory won, no matter how small, would help people understand that the level of inequality that surrounds us has been and always will be a human construct. No force of nature leaves some of us enormously richer than others. We can choose to be more equal. Struggles around pay ratios can make these choices plain.
We can wage these struggles at every level, from local to national, calibrating each campaign to whatever political realities confront us. Lawmakers not ready to impose consequences on private companies with unconscionably wide gaps? Then the struggle starts in the public sector: No one paid with public funds should walk away with more than 10 or 25 or 50 times what any other person in the public sector makes. A 50-times ratio too politically difficult to achieve, in either a public- or private-sector struggle? Then the push becomes a call for a 100-times standard.
No magic, perfect ratio number exists, just as no magic, perfect minimum-wage level exists. Our income floors globally have evolved over time. Our income ceilings will evolve over time as well. And every ceiling we set, in whatever setting, will leave society's remaining sky-high incomes less tolerable -- and more vulnerable.
