Almost all 19th century Chief Justices were not judges. Most notable of that period is Chief Justice Taney who penned the infamous Dred Scott decision. Other notable ones include William Rehnquist and John Marshall (the first Chief Justice, notable cases Marbury v Madison and Hylton).

Unemployment is either equal or greater than the peak unemployment of 1932 in the Great depression at hovering around 25%. Stocks are reacting oddly due to massive influxes of cash even though economic activity is down.

There is no requirements to even be a lawyer let alone judge to be on SCOTUS.

I'm not making the argument about inexperienced but that you don't need to be a judge to become a justice. John Marshall and William Rehnquist for example were not judges prior to their SCOTUS tenures. Most of the Chief Justices in the 19th century had zero judicial experience prior to their tenure as well.
