In 1968, the sanitation workers of Memphis tried to form a union. The city resisted. The Rev. Martin Luther King, Jr. came to support them. That was where he lost his life.

As we segregate by income into different communities, schools in lower-income areas have fewer resources than ever.

We need a national infrastructure bank to rebuild our crumbling highways and water and sewer systems, thereby putting additional people back to work.

Public institutions are supported by all taxpayers and are available to all.

As digital equipment replaces the jobs of routine workers and lower-level professionals, technicians are needed to install, monitor, repair, test, and upgrade all the equipment.

The Tea Party grew out of indignation over the Wall Street bailout - an indignation shared by the vast majority of Americans. But the Tea Party ended up directing its ire at government rather than at big business and Wall Street.

Political scientists after World War II hypothesized that even though the voices of individual Americans counted for little, most people belonged to a variety of interest groups and membership organizations - clubs, associations, political parties, unions - to which politicians were responsive.

If we give up on politics, we're done for. Powerlessness is a self-fulfilling prophesy.

News and images move so easily across borders that attitudes and aspirations are no longer especially national. Cyber-weapons, no longer the exclusive province of national governments, can originate in a hacker's garage.

Harvard, Yale, Princeton, and the rest of the Ivy League are worthy institutions, to be sure, but they're not known for educating large numbers of poor young people.

Our young people - their capacities to think, understand, investigate, and innovate - are America's future.

A society - any society - is defined as a set of mutual benefits and duties embodied most visibly in public institutions: public schools, public libraries, public transportation, public hospitals, public parks, public museums, public recreation, public universities, and so on.

I wish it were simply a nightmare, but I think that any reasonable person watching American politics would come to the conclusion that a second Bush administration would in fact incorporate a more radicalized version of what we've seen in the first administration.

Tax laws favor capital over labor, giving capital gains a lower rate than ordinary income. The rich get humongous mortgage interest deductions while renters get no deduction at all.

It's not government's business what people do in their private bedrooms.

The Tea Party is but one manifestation of a widening perception that the game is rigged in favor of the rich and powerful.

Tea Partiers hate government more than they hate the national debt. They refuse to reduce that debt with tax increases, even with tax increases on the wealthy, because a tax increase doesn't reduce the size of government.

The generosity of the super-rich is sometimes proffered as evidence they're contributing as much to the nation's well-being as they did decades ago when they paid a much larger share of their earnings in taxes.

No company can be expected to build a nuclear reactor, an oil well, a coal mine, or anything else that's one hundred percent safe under all circumstances. The costs would be prohibitive. It's unreasonable to expect corporations to totally guard against small chances of every potential accident.
