Wharton finance professor Joao Gomes warned that the US debt could “break” markets if it continues to grow at the current pace. The debt-to-GDP ratio may double in the next 20 years, reaching an alarming $34 trillion. Public debt already accounts for 121% of GDP, and Bank of America analysts estimate it is growing by around $1 trillion every 100 days.

Billionaire investor Ray Dalio predicted a debt crisis that could hinder US growth.
