The public programs of Franklin Delano Roosevelt's New Deal in the United States have always astounded me. The Works Progress Administration—not only rebuilding the country's infrastructure, creating longterm opportunities in localized projects of repairing bridges, roads and rail lines, or embarking on a mass literacy campaign to educate the impoverished—included support for culture, such as theatre and literature, and a Federal Arts Project with contributions from abstract expressionists such as Jackson Pollock and Mark Rothko.
In a UK presided over by austerity corporatism that concedes to the monopolization of multinational manipulation, unemployment is higher than it has been for decades, while the United States embodies the highest rate of poverty in the developed world. (Reactionary Republicans are unlikely to accept President Obama's somewhat bold and comprehensive jobs program).
With my more detailed elaborations on capitalistic social injustice already available, I will try and be succinct: we should invest in the things that pay for themselves. The investments that create longterm surpluses and reduce deficits. We cannot have economic growth or social development with suppressed if not absolutely impossible social mobility. This being, like the Works Progress Administration, funding the jobs and public programs directly: science, technology and engineering to provide modern and publicly provided transportation, and fully sustainable and renewable forms of energy; support for the arts and humanities, grants to small businesses and entrepreneurs, and provision of universal education.
