Barack Obama is going to solve the economic problems of hardworking Americans, according to his new ad "Dignity":

The ad claims that Obama "helped lift neighborhoods stung by job loss." By "lift" does Obama mean consigned to hell on earth?

The squat brick buildings of Grove Parc Plaza, in a dense neighborhood that Barack Obama represented for eight years as a state senator, hold 504 apartments subsidized by the federal government for people who can't afford to live anywhere else.

But it's not safe to live here.

About 99 of the units are vacant, many rendered uninhabitable by unfixed problems, such as collapsed roofs and fire damage. Mice scamper through the halls. Battered mailboxes hang open. Sewage backs up into kitchen sinks. In 2006, federal inspectors graded the condition of the complex an 11 on a 100-point scale - a score so bad the buildings now face demolition.

Grove Parc has become a symbol for some in Chicago of the broader failures of giving public subsidies to private companies to build and manage affordable housing - an approach strongly backed by Obama as the best replacement for public housing.

As a state senator, the presumptive Democratic presidential nominee coauthored an Illinois law creating a new pool of tax credits for developers. As a US senator, he pressed for increased federal subsidies. And as a presidential candidate, he has campaigned on a promise to create an Affordable Housing Trust Fund that could give developers an estimated $500 million a year.

But a Globe review found that thousands of apartments across Chicago that had been built with local, state, and federal subsidies - including several hundred in Obama's former district - deteriorated so completely that they were no longer habitable.

Grove Parc and several other prominent failures were developed and managed by Obama's close friends and political supporters. Those people profited from the subsidies even as many of Obama's constituents suffered. Tenants lost their homes; surrounding neighborhoods were blighted....

The campaign did not respond to questions about whether Obama was aware of the problems with buildings in his district during his time as a state senator, nor did it comment on the roles played by people connected to the senator.

Not exactly a chicken in every pot and a Prius in every garage, now is it?
