Warren says it’s all about enforcement.  From the story:

“More than half” of the Consumer Financial Protection Bureau’s budget will go toward supervising and enforcing consumer protection rules, said Elizabeth Warren, the White House adviser charged with setting up the nation’s new consumer watchdog agency.

The bureau, set to launch in July to protect consumers from abusive financial practices, will supervise the nation’s largest banks–firms with more than $10 billion in assets. But the consumer protection agency will also need to ensure that thousands of companies that aren’t banks but still offer financial products such as pay day loans, mortgages, student loans and check-cashing services follow federal consumer protection rules as well.
