2020 candidate Sen. Bernie Sanders (I-Vt.) and Rep. Alexandria Ocasio-Cortez (D-N.Y.) — both self-declared Democratic-socialists — will introduce a bill on Thursday to prevent credit card interest rates from rising above 15% and capping consumer loans, the Washington Post reports.

Our thought bubble, via Axios' Felix Salmon: Credit cards are one of the most insidious forms of indebtedness. By bundling a loan with a very convenient payments device, banks deliberately make it easy to rack up large debts and interest charges. Capping rates at 15% would significantly reduce unintentional consumer indebtedness.

Reality check: The proposal illustrates Sanders' enthusiasm when it comes to taking on Wall Street — a consistent theme in his political career. However, it has a slim chance of passing through the Republican-controlled Senate and will most likely face strong resistance from banks.

The bottom line: U.S. card holders are expected to pay $122 billion in interest charges in 2019. That's 12% more than what they paid in 2017 and 50% more than what they paid as recently as 2014.
