A recent report by the Institute for Policy Studies indicates that the richest 20 Americans own more wealth than roughly half the U.S. population combined.  This startling level of economic inequality not only challenges the widely-assumed notion of the United States as an egalitarian society, but undermines democracy, social cohesion, and social mobility.  The vast concentration of wealth also corrupts American politics, leading to government policies that favor the wealthy.

Roughly a century before Bernie Sanders's long-shot run for the White House, another prominent democratic socialist, Eugene V. Debs, waged his own campaigns for the presidency.  Although government repression nearly destroyed what had been a vibrant Socialist Party, in 1920 Debs campaigned for the presidency from his prison cell and drew nearly a million votes.  His campaigns and the popularity of democratic socialism played a key role in sparking America's major economic and social reforms of the 20th century.  

Despite the insistence of the nuclear powers that Iran comply with the nuclear Non-Proliferation Treaty, it is pretty clear that the nuclear-armed countries do not consider themselves bound to comply with this landmark international agreement.  After all, nearly a half-century after the signing of this treaty, which requires that the nuclear powers divest themselves of their nuclear weapons, they not only still possess 16,000 of them but are engaged in a vast, immensely costly buildup of their nuclear arsenals.
