You've given them more than $1 billion. They've given almost nothing to the needy. The 50 worst charities in America devote less than 4 percent of donations raised to direct cash aid. Some charities give even less. Over a decade, one diabetes charity raised nearly $14 million and gave about $10,000 to patients. The worst charity in America operates from a metal warehouse behind a gas station. Every year, Kids Wish Network raises millions of dollars in donations in the name of dying children and their families. Every year, it spends less than 3 cents on the dollar helping kids. Most of the rest gets diverted to enrich the charity's operators and the for-profit companies Kids Wish hires to drum up donations. In the past decade alone, Kids Wish has channeled nearly $110 million donated for sick children to its corporate solicitors. An additional $4.8 million has gone to pay the charity's founder and his own consulting firms. But Kids Wish is not an isolated case, a yearlong investigation by the Tampa Bay Times and The Center for Investigative Reporting has found. These nonprofits adopt popular causes or mimic well-known charity names that fool donors. Then they rake in cash, year after year. Even as they plead for financial support, operators at many of the 50 worst charities have lied to donors about where their money goes, taken multiple salaries, secretly paid themselves consulting fees or arranged fundraising contracts with friends. One cancer charity paid a company owned by the president's son nearly $18 million over eight years to solicit funds.
