Even on Wall Street. Even large ones.
There's a lot of prejudice on the left against large corporations and publicly traded companies. Understandably. However, not all corporations are exploitative to the nth degree. Some are in fact quite good to and for their employees, and for the communities in which they operate.
The mission of a corporation is defined by its corporate charter. Returning value to shareholders is usually part of the charter. However, some companies have social agendas, and/or they make a case that such goals as employee satisfaction add value in the long term and are thus a priority. The belief that corporations only exist for returning profits is an over-simplification. It makes a world of difference how a company goes about making profits, what its vision of its business is, and what its priorities are.
You may have heard of the term
"socially responsible investing" or SRI for short. There are many different SRI funds and screens that are used, for example Calvert's or Domini. And a whole mess of smaller funds and screens that may fit with your values. You can use these as a guide or you can develop your own criteria.
For example, I happen to think employee satisfaction is a good indicator of long term viability and potential for sustained growth, so I look at rankings of that. Also, I pay attention to lists like Fortune's "the 100 best companies to work for" or "100 best companies for women" and there are many other lists like
Working Mother's "Best Companies for Women of Color" and so on. And wouldn't you know it, many Wall Street darlings do in fact make it onto these lists.
Caveats apply. Companies like to put on a good face, there are numerous instances of "greenwashing" and the like, and of course the business press is as full of lies and spin as any other subdomain of the media. But if you're diligent and look at all the angles, you can indentify successful publicly traded corporations that treat their employees with respect and in a real sense provide an environment where workers are valued as human beings.
I think this an area where we can accomplish something politically if we see some of the areas where shareholders as a class and workers as a class are aligned or indeed identical in many cases. Tens of millions of American households in fact participate in the stock market in one form or another. The vast majority of them are not superrich, although typically they would not be living in dire poverty. Most don't exercise much control over the companies that go into their pensions or 401K's. And even when they do have opportunities to invest in SRI funds like TIAA-CREF's (many universities offer this), there are still issues of shareholders' rights and real impedements to exercizing power. A prominent example would be the issue of outrageous CEO compensation. Empowerment can come through coalitions among organized labor, shareholders and public interest groups, all demanding a say in matters of corporate governance.
Really this is an area where I think Edwards is on the right track. An alignment of the middle classes with workers including the working poor against the interests of the superrich is politically stronger than an alignment of, say, the lumpen proletariat and those members of the educated elite who would speak for them. You see Edwards' vision (I'm not speaking of his voting record or any particular stance on labor issues), his vision realisitically jibes with the self perceptions of many Americans. They may have an unrealistic sense of their own wealth and status, and they tend to emulate the wealthy and live a little beyond their means. But the wealth that they do have, they believe that they have earned. That's the key right there. If you can tap into that, and not challenge the assumption (which many of us would recognize as a rationalization for certain priviliges), then you can more easily make the case for aligning with the interests of workers against the people that are frankly robbing us blind.
Once you get the point where you can make the argument one of giving concessions to workers vs. giving huge lumps of money to congenital greedheads who wouldn't use it productively even if they knew how, then your going to sway a lot of people who have a stake in corporate America and you're going to be better positioned to achieve some of your goals of stemming the flow of jobs, allowing workers to organize, to recieve better compensaation and benefits, and to have a more secure infrastructure and safety net that will better the lives of the poor, and all of us in the end.
