"Those credit cards -- don't have them," the prime minister said at a speech in Ankara, Turkey.
"If everybody spends as much as they [banks] want,l they would not even be able to earn that income. They could never be satiated," Erdogan said.
Hurriyet Daily News reported Wednesday that Erdogan said an "interest rate lobby," was supporting plots to weaken Turkey by supporting local protests.
"Who gained from these three weeks of protests? The interest rate lobby, Turkey's enemies," the prime minister said.
"Who lost from these protests? Turkey's economy, and even if to a small extent, tourism lost. They overshadowed and stained Turkey's image and international power," he said.
