Just one in four households eligible for Section 8 housing assistance is getting it and more working Americans are struggling to make rent than at any time since the Great Depression, a new report says on  “Frontline” (PBS, 10 p.m., check local listings). And corruption is part of the reason that affordable housing projects are costing more and producing fewer units, the nine month investigation finds.

NPR reporter Laura Sullivan visits families struggling for affordable housing in Dallas and Miami and finds that some of the tax credits meant to build more units have been funneled to mansions in Costa Rica. Discrimination also plays a large role in the search for housing, says the report titled “Poverty, Politics and Profit.”
