The city of Honolulu is spending $15,000 a week on a crew to clean up tent cities that emerge around Oahu.

It isn't long, however, before homeless people stream right back in because there is no place else for them to go on the small island of glitzy resorts where the cost of living is through the roof.

Honolulu has some shelter and housing programs in place, but there are long waits for services and a shortage of low-income housing for the homeless population that ranks high among other cities in the nation.

Advocates for the homeless say the tent city sweeps aren't working and the money could be better used to aid homeless families.
