California still lets debt collectors empty the bank accounts of poor people. Why?

Erwin Chemerinsky writes for The Sacramento Bee, Sept. 6, 2017

Under current law, the creditor can take all of the money in the bank account. Unlike with wages, there is no requirement that any funds be left to pay for life’s basic necessities. When their bank accounts are completely emptied, individuals often lose the savings that they need to pay for rent or groceries or prescription drugs.
