I can only think the reason it hasn't been fixed is because fraud makes the banks money and they love seeing stories like this.
Well, you would be very wrong. Fraud costs both the retailers and the banks money. The real problem is that issuing new chip cards would cost the banks more than the fraud. Not only are the cards about a dollar more expensive each, and they still have to be re-issued about every three years, but the systems that inject encrypted keys into them, and store the keys on their databases, are very expensive. Banks are notoriously cheap when it comes to spending money that won't make them money.
The other reason EMV hasn't rolled out across the U.S. is that millions of retailers have about 12 million old credit card terminals spread across the country, and most are owned by cheap store owners who don't like being told they have to spend money to replace them. Most retailers have been dragging their feet, not wanting to make an expensive change. But the new members of the breach-of-the-month club are mad about the insecure systems they've been forced to use, and are now championing the rapid switch to EMV instead of fighting it. The smaller retailers are also impacted now, and are no longer resisting.
The irony is that EMV readers for the small retailers are far, far cheaper than the old terminals, and the rates for using new companies like Square, Intuit, and PayPal are much lower than the typical old bank rates for the old credit card readers.
