I do not think Bernie Sanders qualifies as an expert on financial systems and the role liquidity and free markets play. I oppose government bailouts so I’d readily support requirement of adequate reserves and the percentage of capital these large banks have at risk as their cost of doing business for large banks, just like motorists are required to purchase auto insurance. Maybe a bank failure or two not bailed out would be an effective lesson to other “too large to fail” banks that failure IS possible and we WILL let them fail. Government bailouts are not capitalism. They are crony capitalism at best and socialism at the worst.
